Abstract:
Before the advent of reinforced cement concrete and steel structures in the 20th century, structures like Arches, domes and vaults were being widely used worldwide. Arches were mainly used in span openings replacing beams. This was done based on the erstwhile cultural aesthetics and technical development in the prevailing construction methodologies. Nowadays, about 35 to 40 percentage of the total construction cost is being consumed by steel and concrete and therefore constructing a building without steel and concrete contributes to reduction in cost. Vaults and arches do not require concrete and steel but use only bricks and hence environment friendly. This paper deals with the design and construction procedure for structural members including the vault and buttress wall. It also highlights the reduction in cost when adopting vault method over conventional methods, in a residential building. The Vault prototype has been made with the studied design and concepts. The idea is to introduce this technique as a cost reduction approach and to preserve this ancient construction technique. Also, this method will be economical for construction of low cost houses up to two storeys.

Abstract:
Aiming to promote a more sustainable approach to material utilization in architecture, this article presents an alternative construction method for lightweight and efficient concrete structures. The strategic focus is placed on building wide-spanning roof structures like vaults, domes, and freeform shells with the lowest possible input of raw materials and energy. To achieve this objective, the article explores the novel idea of using bending-active structures, made from millimeter-thin carbon fiber strips, as lost formwork and structural reinforcement for the production of hybrid gridshells. After a general introduction to the state-of-the-art in concrete construction, the authors discuss opportunities and challenges related to flexible formwork designs and their possible impacts on the building industry. Relying on the example of a built prototype, the authors present a promising design methodology and analyze the gridshell’s geometrical and structural characteristics throughout different stages of the construction process. The article concludes by discussing the added value of this research and identifying the key aspects that need to be considered in the further development of this construction method.

Abstract:
Concrete shells are a very effective type of building structures due to their ability to bridge large spans with minimal construction thickness. This type of building structures built on the medieval vaulting techniques and, regarding the use of reinforced concrete over the last 100 years, it has overcome the limitations of the masonry vaulting technologies and enabled to increase the span of structures to tens of meters. The construction technology to realize concrete shells using monolithic casting into formwork is besides abovementioned advantages characterized by high labour and thanks to the cost and manufacturing intensity of double curved formwork panels it allows economical realization of only selected structural geometries. Its considerable limitation is, besides the costly production of double curvature formwork, also the laborious installation of formwork and falsework structures. The solution seems to be in line with the upcoming transition to Construction 4.0 robotizing the construction technology of shells that could create a similar increase in productivity and design possibilities as was the technological transition between vaults and shells. One of the promising technologies of robotic production seems to be digital fabrication methods and, in particular, 3D printing or in other words additive manufacturing. This wasteless technology, which has been used to date for experimental projects mainly for the realization of vertical bearing structures, has, despite the first attempts at realizing vaults, a number of technological limitations. In this article, authors aim to summarize and indicate possible constraints of on site 3D printing of domes. They further indicate the possible ways to overcome these limitations and suggest two different means of on site 3D printing of hemispherical dome and the dome based on the catenary profile using extrusion nozzles with different profiles. Finally they discuss the Eurocode requirements for concrete shells and suggest technological solutions for on site 3D printed shells in terms of structural reinforcement.

Abstract:
The principal advances in the design and construction, as well as the static, vibrational, and buckling analysis of thin-walled structures and buildings in the shape of general and axisymmetric ellipsoidal shells are summarized in this review. These shells are particularly useful as internally pressurized vessels or as heads and bottoms of cylindrical tanks and vessels. Reinforced concrete and structural steel domes of buildings, air-supported rubber-fabric shells, and underwater pressure vessels are also made in the form of ellipsoidal, shells. Knowing the geometry of ellipsoids, one can solve various problems in physics, optics, and so on. Basic results of theoretical and experimental investigations of the stress-strain state, buckling, and natural and forced vibrations contained in 209 references are presented in the review. The influence of temperature on the stress-strain state of the shells in question is also discussed. Some parts of the review are also devoted to an analysis of the literature on the stress-strain state of ellipsoidal and torispherical heads of pressure vessels with openings.

Abstract:
Russia has a developed industry of building materials, which today implements an energy- and resource-saving model of its development. The implementation of the state policy of resource conservation is carried out in two main directions: the first direction is to save resources in the production of materials, the second is to increase the production of energy–efficient materials that allow saving energy carriers during their operation. Modern construc-tion in Russia is guided by European construction standards, which, in turn, provides for the construction of ener-gy-saving buildings with minimal energy consumption from external sources. This is ensured by the use of struc-tural and thermal insulation materials in the construction of external walls. In modern structural and thermal insu-lation materials for energy-saving construction, high requirements are imposed on their thermal properties, me-chanical strength and comfort level. From the point of view of simultaneous satisfaction of these requirements, ceramic materials have obvious advantages over other materials, in particular cellular concretes, which, with al-most the same level of thermal conductivity, are characterized by the least hygroscopicity and significantly greater strength. An objective prospect for the development of structural and thermal insulation ceramics is the production of hollow ceramic stones with increased thermal efficiency for their use in economical single-layer external wall structures without additional insulation. The products of individual Ukrainian manufacturers and even imported analogues of the most famous European manufacturer (Wiernerberger Company, Austria), when used in single-layer walls, do not provide regulatory requirements for the heat transfer resistance of masonry for the first temper-ature zone of Russia, which occupies the majority of the territory (60%). This requires the improvement of domes-tic products in the direction of improving their thermal characteristics (reducing thermal conductivity and increas-ing thermal resistance).

Abstract:
The partial replacement of cement in concrete with other building materials has come to light because of research on industrial waste and sustainable building practices. Concrete is made more affordable by using such components, and it also helps to ease disposal worries. Ash made by burning wood and other wood products is one example of such a substance. Many researchers focused on the utilization of wooden ash (WA) as a construction material. However, information is scattered, and no one can easily judge the impact of WA on concrete properties which restrict its use. Therefore, a details review is required which collect the past and current progress on WA as a construction material. relevant information. This review aims to collect all the relevant information including the general back of WA, physical and chemical aspects of WA, the impact of WA on concrete fresh properties, strength properties, and durability aspects in addition to microstructure analysis. The results indicate the WA decreased the slump and increased the setting time. Strength and durability properties improved with the substitution of WA due to pozzolanic reaction and micro-filling effects. However, the optimum dose is important. Different research recommends different optimum doses depending on source mix design etc. However, the majority of researcher suggests a 10% optimum substitution of WA. The review also concludes that, although WA has the potential to be used as a concrete ingredient but less researchers focused on WA as compared to other waste materials such as fly ash and silica fume etc.

Abstract:
One of the new approaches in civil engineering is geodetic domed houses. These are quite economical buildings that most fully reflect the idea of energy saving and the concept of environmentally friendly housing. The symmetry of the sphere allows the most efficient placement of solar panels and solar collectors. The structures of the house are assembled quickly and do not require heavy construction equipment. By reducing the volume of the heating room, we save on heat resources, so the heating of the domed house in the winter requires 20 – 30% less energy in comparison to the rectangular buildings. The purpose of the article is to offer solutions for the development of projects of energy-efficient geo-houses in Ukraine. To search for the most rational design and technological solutions; to analyze the characteristics, advantages and disadvantages of energy efficient geo-house buildings in order to build them in Ukraine. The geodesic dome is made of polyurethane foam, reinforced concrete, wood, fiberglass concrete. Frame structures of the geo-house are made of metal or timber, the "skeleton" is lined with plywood or special OSB-boards. This method provides lightness and strength of the building. The dome must have the optimal size of the ribs, not more than 2.5 m in length, which allows you to erect a frame without the use of technology, with a force of 2 ÷ 3 people. Two installation methods of the frame are considered: connector and non-connector. The proposed solutions for the development of energy-efficient geo-houses' projects in Ukraine will allow in the near future to solve the problems of ecology, energy saving, natural resources saving in the country. Energy-efficient geo-house is the best option for any region of Ukraine, thanks to the undeniable advantages: rigidity and stability of the frame, geometric symmetry of shapes and strength, energy efficiency, high seismic stability, erection speed and originality.

Abstract:
Large-scale suspendomes are elegant architectural structures which cover a vast area with no interrupting columns in the middle. These domes have attractive shapes which are also economical. Domes are built in a wide variety of forms. In this article, an algorithm is developed for optimum design of domes considering the topology, geometry, and size of member section using the cascade-enhanced colliding bodies optimization method. In large-scale space steel structures, a large number of design variables are involved. The idea of cascade optimization allows a single optimization problem to be tackled in a number of successive autonomous optimization stages. The variables are the optimum height of crown and tubular sections of these domes, the initial strain, the length of the struts, and the cross-sectional areas of the cables in the tensegrity system of domes. The number of joints in each ring and the number of rings are considered for topology optimization of ribbed and Schwedler domes. Weight of the dome is taken as the objective function for minimization. A simple procedure is defined to determine the configuration of the domes. The design constraints are considered according to the provisions of Load and Resistance Factor Design–American Institute of Steel Constitution. In order to investigate the efficiency of the presented method, a large-scale suspendome with more than 2266 members is investigated. Numerical results show that the utilized method is an efficient tool for optimal design of large-scale domes. Additionally, in this article, a topology and geometry optimization for two common ribbed and Schwedler domes are performed to find their optimum graphs considering various spans.

Full text
Abstract:
Multi-span precast concrete segmental bridges are commonly constructed using the balanced cantilever method, which essentially involves sequentially extending precast segments outwards from each pier in a balanced manner. A gap of 100 to 200 mm wide is usually provided around the mid-span location between the last two approaching segments to facilitate erection. In-situ concrete is then cast to ‘stitch’ the segments together, thus making the bridge deck continuous. In the current practice, the in-situ concrete stitches are usually designed to be capable of sustaining considerable sagging moment but only minimal hogging moment. Failure of stitches may occur under exceptional circumstances that may potentially trigger a progressive collapse. However, relatively little research in this area has been carried out. In view of this, the author is motivated to undertake an extensive study of the behaviour of in-situ concrete stitches and the effects of their performance on the robustness of typical segmental bridges. Experimental study is carried out to examine the behaviour of in-situ stitches under different combinations of internal forces. Series of stitch specimens of different configurations are tested. Subsequent parametric studies are conducted numerically to examine the effects of various parameters on the load-displacement characteristics of the stitches. Formulae for strength estimation are proposed based on the results. A study of robustness involves analyzing the collapse behaviour of a structure in an extreme event and the analysis should be carried out up to and then well beyond the state of peak strength of structural members. A finite element programme for post-peak analysis is therefore developed for the present study. As the ability of a member section to sustain large inelastic deformation can ultimately affect the robustness of a structure, an investigation is conducted to examine the effects of steel content, yield strength and prestressing level on the ductility and deformability of prestressed concrete sections. Using the programme developed, the formation of collapsing mechanisms of a multi-span segmental bridge deck in an extreme event is examined. A typical bridge deck is subject to prescribed accidental load on its span in order to analyze the sequence of failure. Substantial redistribution of internal forces along the deck is observed as failures initiate, thus causing subsequent failures of other deck sections even though they have been designed to resist the internal forces at the ultimate limit state. The results indicate that any span of a multispan bridge may become a temporary end-span in the event of collapse of an adjacent span and the strength of the sections must be designed accordingly to prevent progressive failure. As a span becomes a temporary end-span, the in-situ concrete stitches may experience substantial moment and shear, and their failure could potentially trigger progressive collapse of the entire bridge deck. Towards the end of the thesis, important design considerations that can enhance the performance of in-situ concrete stitches and robustness of precast concrete segmental bridges are presented.

Abstract:
Self-compacting concrete (SCC) can flow into place and compact under its own weight into a uniform void free mass even in areas of congested reinforcement. The research reported in this thesis examined the production of SCC with readily available UK materials, with the overall aims of evaluating test methods and establishing a suitable mix design procedure. There have been significant recent developments and applications of SCC in several countries, notably Japan. A literature survey gave an understanding of the advantages and properties of SCC, test methods and the range of constituent materials and their relative proportions for its successful production. A range of SCC mixes can be produced with the common features of a lower aggregate content than conventional concrete and the use of superplasticizers. Most mixes also contained one or more of pulverized fuel ash, ground granulated blast furnace slag and an inert powder filler. A four stage experimental programme was carried out: *tests on pastes to assess the effect of the types and proportions of the powders and superplasticizers on the rheology. *tests on mortars to determine suitable dosage of superplasticizers for high fluidity, low segregation and low loss of workability with time after mixing. Flow spread and funnel tests were used. *tests on fresh concrete to enable suitable types and quantities of coarse aggregate to be combined with these mortars to produce SCC. Fluidity and viscosity were measured using slump flow and V-funnel tests, and passing ability using L- and U-type tests. Two-point workability tests were also carried out, and a novel way of assessing segregation resistance was developed. *tests on hardened concrete to determine compressive strength, bond to reinforcement and drying shrinkage. A mix design procedure, based on a method suggested by Japanese workers, has been developed. This includes optimisation of the mix with a linear optimisation tool from a commercial spreadsheet package.

Full text
Abstract:
Harmony search method based optimum topology design algorithm is presented for single layer lamella domes. The harmony search method is a numerical optimization technique developed recently that imitates the musical performance process which takes place when a musician searches for a better state of harmony. Jazz improvisation seeks to find musically pleasing harmony similar to the optimum design process which seeks to find the optimum solution. The optimum design algorithm developed imposes the behavioral and performance constraints in accordance with LRFD-AISC. The optimum number of rings, the height of the crown and the tubular cross-sectional designations for dome members are treated as design variables. The member grouping is allowed so that the same section can be adopted for each group. The design algorithm developed has a routine that build the data for the geometry of the dome automatically that covers the numbering of joints, and member incidences, and the computation of the coordinates of joints. Due to the slenderness and the presence of imperfections in dome structures it is necessary to consider the geometric nonlinearity in the prediction of their response under the external loading. Design examples are considered to demonstrate the efficiency of the algorithm presented.

Abstract:
A fully automated computer program is developed for the optimum design of steel space trusses acting compositely with a concrete slab placed on top. The program sizes the truss members to meet the requirements of the load and resistance factor design specification of the American Institute of Steel Construction using the load combinations of ANSI. Earthquake loading is not considered. The optimum size is based on minimum cost, regarding the amount of welding required at the joints and of the member itself. The total cost is based on all steel work in the truss. Once the truss configuration has been defined, and it has been ensured that linear elastic behavior exists, the structure is analyzed for the construction process, to make sure that no overstressing will take place in any structural element at any time during construction and service. The analysis and design principles are presented and an actual design case is solved. (Abstract shortened with permission of author.)

Abstract:
Tilt-up construction features the use of factory or site cast (not precast) reinforced concrete panels that are tilted about one edge and/or lifted into position to form the walls of a building. This method of construction benefits the builder by offering time and cost savings. It is also attractive to architects because of the variety of surface finishes and panel shapes that can be achieved. Due to this versatility, Tilt-up construction has evolved from its beginnings in factory buildings to sophisticated commercial and multi-unit residential construction. With the continuing growth in Tilt-up construction, there is a need to assess the potential benefits to the home owner of an energy efficient design using the thermal mass properties of concrete Tilt-up panels. Tilt-up will reach its full potential as an energy efficient form of construction when the short term cost savings to the builder are combined with the long term energy savings to the home owner. The objective of this work is to undertake an innovative energy efficient design of a residential Tiltup building in the form of a fully detached single storey house. The project will assess the benefits and the problems of combining residential Tilt-up construction with energy efficient design principles by comparing the results to a conventional design approach. Specific objectives include: • Identification of design elements of energy efficient design and tilt-up construction, • Development of performance indicators to optimise the design and assess the relative benefits and costs of combining energy efficient design and tilt-up construction, • Selection of a proven energy efficient house based on a conventional design approach, • Design of an appropriate Tilt-up construction method for the selected energy efficient house, and • Optimisation of the design by the application of performance indicators to the design elements. In the first instance, it is necessary to determine an appropriate design strategy that will meet the above objectives. The work involves the design of a fully detached single storey house in Perth, Western Australia. Therefore, the design strategy must be relevant to Perth's climatic, social, political and economic conditions. In this light, an Australian rather than an overseas based approach, provides the most appropriate starting point for the research and design task. Developments overseas are assessed with respect to specific design tools and options that may enhance the flexibility, results and applicability of the adopted design approach. Section 2 develops the design strategy for an energy efficient design of a fully detached single storey house incorporating Tilt-up construction. Design strategies in use in Australia that achieve the separate objectives of energy efficient design and Tilt-up construction are identified and specific design. tools and options are assessed. In particular, strengths, weaknesses, limitations and assumptions of available strategies are discussed with respect to the above objectives. A design strategy combining the objectives of energy efficient design and Tilt-up construction is developed together with a consolidated list of common and exclusive design elements. In addition, a multi-objective assessment criteria in the form of performance indicators is introduced to optimise and assess the design. Once the design strategy is developed, it is then necessary to determine how each design element is judged by the assessment criteria. Section 3 develops the assessment framework by assigning, where appropriate, quantitative or qualitative measures to the performance indicators. This establishes the mechanism by which each design element is addressed in terms of the performance indicators. Factors that conflict with, or complement other performance indicators are identified and where possible, quantified. Where required, trade-offs are assessed and adopted. In this way the design task is optimised and assessed in an iterative process to meet the assessment criteria. Section 4 details the design of the Tilt-up house, including optimisation of design elements to meet performance indicators. The selection criteria for a proven energy efficient design to form the base case design is outlined. In addition, the results of the conversion from conventional to Tilt-up construction are discussed and guiding strategies that provide opportunities for further optimisation are identified. Finally, the results of applying appropriate guiding strategies to further optimise the base case design are detailed. It is important to note that due to professional liability limitations on the author, only a preliminary structural design is attempted in this work. If the house is to be constructed, then this will require a detailed structural design that will be the responsibility of an independent professionally certified structural engineer. Section 5 summarises the results of optimising the design and discusses the extent to which each performance indicator has been met. Specifically, the benefits and costs of combining energy efficient design with Tilt-up construction are assessed. Section 6 draws a number of conclusions and makes recommendations for the application of the results and for further work based on the results discussed in Section 5.

Abstract:
A 3,000 sq.ft., two-story monolithic thin-shell concrete dome custom home was constructed in 2005 in Mesa, AZ, by the author. This architectural construction style represents a small, but growing, commercial and residential market, one of whose selling points is energy efficiency. During the preliminary architectural design phase, the only anecdotal and case studies available to the author were mainly related to cold-weather climates. No technically adequate thermal performance studies were found for the opposite, high temperature extreme of climate conditions. To address this need, two models are developed and explored. First, a preliminary lumped-parameter model (initially created to lend technical credence to the exuberant claims of dome aficionados and provide rationalization for the custom home construction project), is compared with actual data collected at the dome during construction. Because the correlation is not very good, a second model based on thermal two-port transmission line theory, is developed. This model provides additional insight, and in particular, comparison with the actual data suggests that model verification will require a somewhat different approach to data collection itself (and to the manner in which the model is utilized). This is confirmed using a small set of subsequent trial data. Thermal models aside, actual utility consumption data for the dome is compared with two conventional block-construction homes in the same geographic locale, showing that the dome thermal performance, at least during the hot months of the year, provides a measurable advantage. Finally, it is shown how the transmission line model makes it very easy to explore the thermal effects of reversing the order of the primary material layers (insulation and concrete).

Full text
Abstract:
Abstract Vibration transmitted from underground railways into nearby buildings is an increasingly significant problem affecting high-value residential and commercial developments. Various forms of vibration isolation are used in underground railways, one of which is the ‘floating slab track’. Rails are fixed directly to a massive concrete slab which in turn rests on a resilient mounting (usually rubber bearings or steel springs) so isolating the track from the tunnel invert. The effectiveness of vibration attenuation does not compare well with the simple mass-spring models typically used in the design of floating slab track. This paper develops a model for floating slab track by conceptualising the track as two infinite beams (representing the rail and the concrete slab) separated by elastic layers representing the resilient elements used in floating slab track construction. A dynamic model for a finite-length unit of track is obtained from this physical model by the dynamic-stiffness-matrix method. A repeating unit method is utilised to create track models of infinite length from the finite track unit, an approach which much reduces the computation required. A concept of total force transmitted to the ground for a given set of inputs on the rail is developed, and the effect of various track parameters on the transmitted force is examined.

Abstract:
<p>For improved safety and ease of travel for pedestrians and cyclists across the busy 4-lane main road Breidholtsbraut in the suburb of Breidholt in Reykjavik, Iceland, the Icelandic Road and Coastal Administration and Reykjavik City Council engaged EFLA Consulting Engineers and Studio Granda Architects for the design of a footbridge over the road. The bridge is an 86-m long, post-tensioned concrete girder in four spans and follows a curved alignment that plays on the landscaped surroundings. The attractive shape of the underside of the concrete girder is formed by a series of arcs; the cross-section having been used before by the design team to good effect. Aiming for minimized inspection and maintenance costs, the end abutments of the bridge are supported through a concealed concrete hinge, eliminating the need for bearings and construction joints. The stainless-steel wire mesh handrail was embedded into the concrete deck post casting, using a carefully planned core drilling procedure. The bridge does not have a support in the road central reserve, and this has allowed the bridge construction to proceed with only a few, short closures of the busy underlying road. The result is a well-received addition to the collection of Reykjavik footbridges.</p>

Full text
Abstract:
Prestressed reinforced concrete containment is an important part among the safety-related buildings, and the presressing technology is widely used in containment construction which is best suited to the cylindrical-type containment topped by a dome. It has been recognized that traditional methods for analysis of containment prestressing system have been unable to satisfy more accurate design, research and monitoring requirements. Prestressing tendons are placed complexly in containment structure, especially near the major equipment hatch area, which is the three-dimensional curve and the friction loss must be considered. Firstly, containment structure and the distribution of prestresseing system are introduced briefly. Furthermore, the calculating process of prestressing tendons losses is put forward in details which take the major equipment hatch as an example. Solid65 element and constitutive model of concrete in ANSYS are introduced in details, and the characteristic of simulating prestressing tendons in ANSYS is analyzed. Based above study, finite element model of the prestressed structure is built based on some concrete containment by using ANSYS program, the prestressing effect on concrete containment is put forward. The numerical results show that most of the design pressure is beared by the prestressing system under the design-basis pressure condition, and the simulation method is effective with a high accuracy which agrees well with stress tests performed on-site in some operating NPPs such as LINGAO PHASE II.

In 12th international conference on ‘Advances in Steel-Concrete Composite Structures’ - ASCCS 2018. Valencia: Universitat Politècnica València, 2018. http://dx.doi.org/10.4995/asccs2018.2018.7127.

Full text
Abstract:
Composite floors are often used in building construction where beams typically span from 6 to 18 m. They are commonly used together with decking of 50 to 80 mm depth that spans 3 to 4.5 m between the beams. Rules for the minimum degree of shear connection in composite beams are presented in Eurocode 4 and other international Codes, and were derived for beams in propped construction.Eurocode 4 defines a minimum limit for the degree of shear connection, primarily to ensure that slip at the steel-concrete interface does not exceed a limiting value. This limit is proportionate to the beam span and also depends on the steel strength and the asymmetry of the flange areas of the section. Currently, many designs cannot achieve the codified degree of shear connection demands, since it is not possible to accommodate a sufficient number of shear connectors on the span as dictated by the spacing of the deck ribs. However, there are special cases which are not explicitly accounted for in Codes. This paper aims to investigate the degree of shear connection requirements in such cases, including beams that are unpropped in construction, beams that are not fully utilised in bending because serviceability criteria govern their design and beams that are predominantly loaded by point loads rather than uniform loading.The results from parametric finite element analyses carried out using ANSYS for beams in the span range of 6 to 18 m are presented. The finite element models have been calibrated against composite beam tests. Comparisons are made with the current Eurocode 4 provisions and modifications are proposed where appropriate.

Abstract:
Case studies of structure failures due to accidental actions are presented in the paper. Bad design does not mean only errors of computation, but incorrect theories or confidence in inaccurate data. The bridge structure failure during concrete pouring due to combination of the above reasons proves this statement. The next example of a sufficiently designed and constructed temporary platform illustrates importance of proper operations. Even an excellently constructed hall could not stand on bad foundations. Some failures are not the result of poor project, but the consequence of unforeseen events that create uncommon loads on structures. But, the main goal of the paper is to help construction engineers, workers, project managers, and regulatory bodies identify problems in construction design, project execution and management of field engineering practise.

Full text
Abstract:
The Spinnanker is a new developed foundation and anchor system to lead forces into the subsoil. The Spinnanker can be installed almost on ervery type of terrain, even on steep slopes, in nearly all kinds of subsoil material. Based on comprehensive theoretical analysis and in-situ field tests the load deformation behaviour of the Spinnanker has been defined. Up to now more than 4,000 Spinnanker have been installed for permanent and temporary construction tasks. The Spinnanker consists of a steel plate and 6 or 12 steel bars with a length of up to 8 m. For the installation the steel bars are screwed into the subsoil. One person can install the Spinnanker in less than one hour without using any heavy equipment. The system does not need any concrete and can be removed totally without any parts remaining in the subsoil. The paper presents the theoretical approaches, the developed principle of the design and the application in engineering practice. For example the Spinnanker is used for anchoring and foundation of houses, farming and fabrication halls, slope stabilisation, auxiliary constructions (e.g. for overhead electricity line towers) and fixed-points for construction machines.

Full text
Abstract:
This report describes the design, construction, and shaking table response and computation simulation of a Low Seismic-Damage Bridge Bent built using Accelerated Bridge Construction methods. The proposed bent combines precast post-tensioned columns with precast foundation and bent cap to simplify off- and on-site construction burdens and minimize earthquake-induced damage and associated repair costs. Each column consists of reinforced concrete cast inside a cylindrical steel shell, which acts as the formwork, and the confining and shear reinforcement. The column steel shell is engineered to facilitate the formation of a rocking interface for concentrating the deformation demands in the columns, thereby reducing earthquake-induced damage. The precast foundation and bent cap have corrugated-metal-duct lined sockets, where the columns will be placed and grouted on-site to form the column–beam joints. Large inelastic deformation demands in the structure are concentrated at the column–beam interfaces, which are designed to accommodate these demands with minimal structural damage. Longitudinal post-tensioned high-strength steel threaded bars, designed to respond elastically, ensure re-centering behavior. Internal mild steel reinforcing bars, debonded from the concrete at the interfaces, provide energy dissipation and impact mitigation.

Huang, Cihang, Yen-Fang Su, and Na Lu. Self-Healing Cementitious Composites (SHCC) with Ultrahigh Ductility for Pavement and Bridge Construction. Purdue University, 2021. http://dx.doi.org/10.5703/1288284317403.

Full text
Abstract:
Cracks and their formations in concrete structures have been a common and long-lived problem, mainly due to the intrinsic brittleness of the concrete. Concrete structures, such as rigid pavement and bridge decks, are prone to deformations and deteriorations caused by shrinkage, temperature fluctuation, and traffic load, which can affect their service life. Rehabilitation of concrete structures is expensive and challenging—not only from maintenance viewpoints but also because they cannot be used for services during maintenance. It is critical to significantly improve the ductility of concrete to overcome such issues and to enable better infrastructure quality. To this end, the self-healing cementitious composites (SHCC) investigated in this work could be a promising solution to the aforementioned problems. In this project, the team has designed a series of cementitious composites to investigate their mechanical performances and self-healing abilities. Firstly, various types of fibers were investigated for improving ductility of the designed SHCC. To enhance the self-healing of SHCC, we proposed and examined that the combination of the internal curing method with SHCC mixture design can further improve self-healing performance. Three types of internal curing agents were used on the SHCC mixture design, and their self-healing efficiency was evaluated by multiple destructive and non-destructive tests. Results indicated a significant improvement in the self-healing capacity with the incorporation of internal curing agents such as zeolite and lightweight aggregate. To control the fiber distribution and workability of the SHCC, the mix design was further adjusted by controlling rheology using different types of viscosity modifiers. The team also explored the feasibility of the incorporation of colloidal nano-silica into the mix design of SHCC. Results suggest that optimum amounts of nano-silica have positive influence on self-healing efficiency and mechanical properties of the SHCC. Better hydration was also achieved by adding the nano-silica. The bonding strength of the SHCC with conventional concrete was also improved. At last, a standardized mixing procedure for the large scale SHCC was drafted and proposed.

Full text
Abstract:
A research investigation was conducted on the erosion potential of stabilized subbases under concrete pavements and asphalt layers supporting concrete overlays. Through field surveys and testing in Illinois, this project evaluated if existing concrete pavements with stabilized subbases and concrete overlays were exhibiting potential erosion of the underlying support layer. The field evaluation testing included falling weight deflectometer testing, distress surveys, coring, and ultrasonic tomography scanning. A laboratory performance test was also established using the Hamburg wheel-tracking device to assess the erodibility of the various stabilized subbase layers for new construction and existing asphalt layers available for a concrete overlay. The analyzed field test results were coupled together with the laboratory performance testing to provide recommendations for updating the Illinois Department of Transportation’s “Bureau of Design and Environment Manual” guidance. No changes were recommended for hot-mix asphalt stabilized subbases, but testing using the Hamburg wheel-tracking device should be considered for Portland cement concrete stabilized support layers (e.g., CAM II) under concrete pavements. For testing of asphalt support layers for concrete pavement overlays, the Hamburg wheel-tracking device is recommended with performance criteria similar to flexible pavements for appropriate functional classes.

Abstract:
This research project conducted laboratory testing on the design and impact of internal curing on concrete paving mixtures with supplementary cementitious materials and evaluated field test sections for the performance of crack properties and CRCP structure under environmental and FWD loading. Three experimental CRCP sections on Illinois Route 390 near Itasca, IL and two continuously reinforced concrete beams at UIUC ATREL test facilities were constructed and monitored. Erodibility testing was performed on foundation materials to determine the likelihood of certain combinations of materials as suitable base/subbase layers. A new post-tensioning system for CRCP was also evaluated for increased performance and cost-effectiveness. This report volume summarizes the three year research effort evaluating design, material, and construction features that have the potential for reducing the initial cost of CRCP without compromising its long-term performance.

Abstract:
The Sagamore Parkway Bridge consists of twin parallel bridges over the Wabash River in Lafayette, IN. The old steel-truss eastbound bridge was demolished in November 2016 and replaced by a new seven-span concrete bridge. The new bridge consists of two end-bents (bent 1 and bent 8) and six interior piers (pier 2 to pier 7) that are founded on closed-ended and open-ended driven pipe piles, respectively. During bridge construction, one of the bridge piers (pier 7) and its foundation elements were selected for instrumentation for monitoring the long-term response of the bridge to dead and live loads. The main goals of the project were (1) to compare the design bridge loads (dead and live loads) with the actual measured loads and (2) to study the transfer of the superstructure loads to the foundation and the load distribution among the piles in the group. This report presents in detail the site investigation data, the instrumentation schemes used for load and settlement measurements, and the response of the bridge pier and its foundation to dead and live loads at different stages during and after bridge construction. The measurement results include the load-settlement curves of the bridge pier and the piles supporting it, the load transferred from the bridge pier to its foundation, the bearing capacity of the pile cap, the load eccentricity, and the distribution of loads within the pier’s cross section and among the individual piles in the group. The measured dead and live loads are compared with those estimated in bridge design.

Long-term performance of sustainable pavements using ternary blended concrete with recycled aggregates.

Full text
Abstract:
Dwindling supplies of natural concrete aggregates, the cost of landfilling construction waste, and interest in sustainable design have increased the demand for recycled concrete aggregates (RCA) in new portland cement concrete mixtures. RCA repurposes waste material to provide useful ingredients for new construction applications. However, RCA can reduce the performance of the concrete. This study investigated the effectiveness of ternary blended binders, mixtures containing portland cement and two different supplementary cementitious materials, at mitigating performance losses of concrete mixtures with RCA materials. Concrete mixtures with different ternary binder combinations were batched with four recycled concrete aggregate materials. For the materials used, the study found that a blend of portland cement, Class C fly ash, and blast furnace slag produced the highest strength of ternary binder. At 50% replacement of virgin aggregates and ternary blended binder, some specimens showed comparable mechanical performance to a control mix of only portland cement as a binder and no RCA substitution. This study demonstrates that even at 50% RCA replacement, using the appropriate ternary binder can create a concrete mixture that performs similarly to a plain portland cement concrete without RCA, with the added benefit of being environmentally beneficial.

Abstract:
This report summarizes activities undertaken to support and ensure that the Illinois Department of Transportation utilizes the best demonstrated available technology for design and construction of full-depth hot-mix asphalt (HMA) pavements and HMA pavements on rubblized Portland cement concrete pavement (PCCP). To achieve this goal, the researchers reviewed pavement design and special provisions for full-depth asphalt and rubblization projects as well as full-depth asphalt and rubblization project performance via condition surveys and deflection measurements. They also modified design inputs as needed from the review of literature and responded to specific issues related to full-depth asphalt and rubblization design and construction. The researchers studied 32 rubblization projects on the interstate system and found this rehabilitation technique is providing good to excellent performance that exceeds design expectations. They provided input on proposed changes to full-depth hot-mix asphalt pavement on rubblized PCCP specifications as well as provided input on the RoadTec 1105e material transfer device. Analysis of traffic speed deflectometer data obtained on several hot-mix asphalt and rubblized pavements resulted in the development of analysis algorithms.

DeSantis, John, and Jeffery Roesler. Longitudinal Cracking Investigation on I-72 Experimental Unbonded Concrete Overlay. Illinois Center for Transportation, February 2022. http://dx.doi.org/10.36501/0197-9191/22-002.

Full text
Abstract:
A research study investigated longitudinal cracking developing along an experimental unbonded concrete overlay (UBOL) on I-72 near Riverton, Illinois. The project evaluated existing literature on UBOL (design, construction, and performance), UBOL case studies, and mechanistic-empirical design procedures for defining the mechanisms that are contributing to the observed distresses. Detailed distress surveys and coring were conducted to assess the extent of the longitudinal cracking and faulting along the longitudinal lane-shoulder joint. Coring over the transverse contraction joints in the driving lane showed stripping and erosion of the dense-graded hot-mix asphalt (HMA) interlayer was the primary mechanism initiating the longitudinal cracks. Cores from the lane-shoulder joint confirmed stripping and erosion was also occurring there and leading to the elevation difference between the driving lane and shoulder. Field sections by surrounding state departments of transportation (DOTs), such as Iowa, Michigan, Minnesota, Missouri, and Pennsylvania, with similar UBOL design features to the I-72 section were examined. Site visits were performed in Illinois, Michigan, Minnesota, and Pennsylvania, while other sections were reviewed via state DOT contacts as well as Google Earth and Maps. Evidence from other DOTs suggested that HMA interlayers, whether dense graded or drainable, could experience stripping, erosion, and instability under certain conditions. An existing performance test for interlayers, i.e., Hamburg wheel-tracking device, and current models reviewed were not able to predict the distresses on I-72 eastbound. Adapting a dynamic cylinder test is a next step to screen HMA interlayers (or other stabilized layers) for stripping and erosion potential. To slow down the cracking and faulting on I-72 eastbound, sealing of the longitudinal lane-shoulder joint and driving lane transverse joints is suggested. To maximize UBOL service life, an HMA overlay will minimize water infiltration into the interlayer system and significantly slow down the HMA stripping and erosion mechanism that has led to longitudinal cracking and lane-shoulder faulting.
