Abstract:
Purpose Concrete arch structures are commonly constructed for various civil engineering applications. Despite their frequent use, there is a lack of research on the response and performance of concrete arches when subjected to fire loading. Hence, this paper aims to investigate the response and in-plane failure modes of shallow circular concrete arches subjected to mechanical and fire loading. Design/methodology/approach This study is conducted through the development of a three-dimensional finite element (FE) model in ANSYS. The FE model is verified by comparison to a non-discretisation numerical model derived herein and the reduced modulus buckling theory, both used for the non-linear inelastic analysis of shallow concrete arches subjected to uniformly distributed radial loading and uniform temperature field. Both anti-symmetric and symmetric buckling modes are examined, with analysis of the former requiring geometric imperfection obtained by an eigenvalue buckling analysis. Findings The FE results show that anti-symmetric bifurcation buckling is the dominant failure mode in shallow concrete arches under mechanical and fire loading. Additionally, parametric studies are presented which illustrate the influence of various parameters on fire resistance time. Originality/value Fire response of concrete arches has not been reported in the open literature. The authors have previously investigated the stability of shallow concrete arches subjected to mechanical and uniform thermal loading. It was found that temperature greatly reduced the buckling loads of concrete arches. However, this study was limited to the simplifying assumptions made which include elastic material behaviour and uniform temperature loading. The present study provides a realistic insight into the fire response and stability of shallow concrete arches. The findings herein may be adopted in the fire design of shallow concrete arches.

Abstract:
Washington enjoys a unique international focus as a city planned for beauty. It incorporates a monumental baroque plan superimposed on a topography bordered by rivers and hills. Marble monuments and governmental structures carefully range a tree-lined formal landscape in the city's core. Fiercely protected height limits assure as a centerpiece the Capitol dome and monument-lined Mall. Conscious planning and architectural aesthetic effort have resulted in bridges that are an integral part of the nation's capital in 1996. Its structures reveal history, engineering excellence, and undeniable aesthetic import. Six bridges defend this thesis: Arlington Memorial Bridge, sculpture and arches formally carrying the Mall across the Potomac River; Francis Scott Key Bridge, high concrete arches whose silhouette are a major feature of the Potomac Palisades; William Howard Taft Bridge, engineering tour de force (largest unreinforced concrete structure in the world), carrying one of the city's main avenues across Rock Creek Park on multiple arches; Dumbarton Bridge, integrating architecture and sculpture in the parkscape while solving a street misalignment across Rock Creek Park; Connecticut Avenue Bridge over Klingle Valley, Art Deco steel-arched structure; and John Phillip Sousa Bridge, early 20th century axial connection of Pennsylvania Avenue, S.E., over the Anacostia River. Steel, concrete, arches, and trusses make up the aesthetic components of these structures, each in a unique visual context.

Abstract:
Increasingly, research indicates that steel fibers can significantly enhance the engineering properties of mortar and concrete; however, few studies have examined their impact on the reinforcement of in-service tunnel linings within sleeve arch structures. In this study, a series of 1:2 scale experiments were conducted using a specialized loading device to compare the reinforcement performance of steel fiber-reinforced concrete sleeve arches and traditional reinforced concrete sleeve arches on prefabricated cracks with depths of 1/3 and 2/3 of the lining thickness. The experimental results were validated using numerical simulations. The results indicate that under the same load, when reinforcing components with 2/3 prefabricated cracks, the maximum compressive strains for steel fiber-reinforced and reinforced concrete sleeve arches were −852 με and −985 με, respectively, and the maximum deflections were 3.57 mm and 5.48 mm. Composite sleeve arches of both materials provide a certain degree of reinforcement to linings with varying damage. The reinforcement performance of steel fiber-reinforced concrete sleeve arches is superior to that of traditional reinforced concrete sleeve arches, with particularly significant reinforcement for linings with 2/3 prefabricated cracks. Numerical simulations have shown that the stress in reinforced concrete at the concentrated stress regions is 16.15%, 6.01%, 12.68%, 36.62%, and 4.82% higher than that in steel fiber-reinforced concrete, respectively, thereby validating the reliability of the experimental results. Therefore, this study recommends the application of steel fiber materials in sleeve arches to achieve superior maintenance and reinforcement, addressing cracking issues in in-service tunnel linings and thereby improving the safety and durability of these structures.

Abstract:
Objective. A new method of manufacturing arches for a fiber-reinforced concrete bridge in the form of an analogue of permanent formwork is considered. Within the framework of this work, research results have been obtained that confirm the effectiveness of the system for the construction of bridge arches of various configurations.Method. The proposed developments will improve the strength characteristics of the bridge arch for small and medium bridges by optimizing the shape and size of the cross section in accordance with the change in the bending moment along the length of the arch. At the same time, reduce its metal consumption by several times.Result. The results obtained confirmed the effectiveness of electrostatic spraying of dry concrete mixture with simultaneous moisture up to moisture, which contributes to the work of capillary forces for compaction of concrete layers and the manufacture of a profiled strong shell (analogue of non-removable reinforced formwork) from reinforced fiber-reinforced concrete.Conclusion. By varying the shape and dimensions of the cross- section, the thickness of the shell and the degree of its reinforcement, as well as filling this shell with high-strength fiber-reinforced concrete, it is possible to design and manufacture bridge arches for various loads.

Abstract:
Cracking of bolt holes is a very common form of distress in pipe-arch type of soil–steel structures, the conduit walls of which are subjected to very large radial soil pressures in their lower haunches. This paper, in discussing the mechanics of this form of distress, concludes that the cracks are formed mainly due to the inability of the soil in the haunch areas to sustain the very high pressures. It also contains methods to alleviate these problems, both at the design and at the construction stage. Guidelines for proper bolt arrangements are given, and use of low-strength concrete around and under the haunches is recommended. Pouring of concrete in segments is suggested to avoid potential flotation of the pipe during construction. A case history incorporating this measure is given to demonstrate its feasibility. Key words: soil–steel structure, pipe-arch, culvert, highway bridges, bolt-hole tears.

Abstract:
An inverse first order reliability method (FORM) is presented to solve the safety factors for the in-plane creep stability of concrete filled steel tubular (CFST) arches. In the inverse analysis, the safety factors with or without considering the time-dependent behavior of concrete are introduced into limit state equations for the in-plane stability design of CFST arches. For different target reliability indices and steel ratios, the time-independent and time-dependent safety factors are solved. The results show that the inverse FORM is of good efficiency and applicability. The target reliability indices have little effect on the safety factors for the creep stability of CFST arches. The effects of steel ratios are significant which should be considered in design. For the commonly used steel ratios of CFST arches, the in-plane safety factors for creep stability range from 1.17 to 1.43.

Arco segmentado é uma estrutura composta de vários segmentos retilíneos,emendados em pontos pertencentes a uma curva em forma de arco que circunscreve a estrutura. A coincidência dos pontos das emendas (nós) com essa curva permite a redução dos momentos fletores nesses pontos. O arco segmentado assim idealizado apresenta algumas vantagens para a indústria de pré-moldados, quais sejam: permite a utilização das fôrmas empregadas na moldagem de outros tipos de peças retilíneas como pilares e vigas; permite a construção de arcos com qualquer relação entre a flecha e o vão, empregando-se as mesmas fôrmas, bastando para isso variar os ângulos entre os segmentos emendados. Neste trabalho é feito um estudo teórico sobre a estabilidade dos arcos segmentados,utilizando para isto o modelo computacional baseado no método nos elementos finitos. Dentro deste estudo são realizadas análises sobre a influência da relação altura/vão, da variação do número de segmentos, da presença de imperfeições iniciais e da ação do vento no comportamento global destes arcos. Também é desenvolvido um procedimento para o cálculo da carga crítica dos arcos segmentados bi e tri-articulados e que leva em consideração tanto as cargas caracterizadas por pontos limite como as por pontos de bifurcação. São apresentados os detalhes e resultados de um ensaio experimental de um arco segmentado de concreto armado, que teve como objetivo principal a verificação do comportamento global deste tipo de estrutura e da eficiência do modelo computacional aqui utilizado.
Segmental arch is a structure made of several straight segments of precast concrete connected at points belonging to a curve in the form of an arch which circumscribes the structure. This type of arch has some advantages for the precasting industry: a) it allows the use of the same forms used to cast other types of straight pieces such as beams and columns; b) it allows the construction of arches with any height/span ratio, using the same forms, which is achieved just by varying the angle between the connected segments. In this work, a study of the stability of this type of arch is developed, with the use of a computer model based on the finite elements method. In side of this study, the effects of height/span ratio variation, segment number variation, initial imperfections presence and the wind action are investigated. In addition, a calculus procedure of the critical load to the segmental arches is developed. This procedure takes in consideration the loads characterized by limit points as much as that by bifurcation points. Is also presented an experimental test, of a segmental arch made of reinforced concrete, that was conducted with the purpose of studying the global behavior of this type of structure, and verify the efficiency of the computer model used.

Abstract:
A rigorous structural analysis is fundamental in the safety assessment of the built heritage and in its efficient conservation and rehabilitation. In line with the necessity of refined techniques, the objective of the present thesis is to develop and validate, in a displacement-based finite element framework, a nonlinear model apt for the study of masonry and concrete structures under monotonic and cyclic loading. The proposed constitutive law adopts two independent scalar damage variables, d+ and d−, in combination with the spectral decomposition of the elastic strain tensor, to simulate the pronounced dissimilar response under tension and compression, typical of these materials. The assumption of energy-equivalence between the damaged solid and the effective (undamaged) one is considered for representing the orthotropy induced in the material by the degradation process, with the consequence that a thermodynamically consistent constitutive operator, positive definite, symmetric and strain-driven, is derived. The formulation is integrated with a multidirectional damage procedure, addressed to extend the microcrack closure-reopening (MCR) capabilities to generic cyclic conditions, especially shear cyclic conditions, making the model suitable for dealing with seismic actions. Maintaining unaltered the dependence of the constitutive law from d+ and d−, this approach activates or deactivates a tensile (compressive) damage value on the base of the current maximum (minimum) principal strain direction. In correspondence with damage activation (crack opening) or deactivation (crack closure), a smooth transition is introduced, in order to avoid abrupt changes in stiffness and enhance the numerical performance and robustness of the multidirectional procedure. Moreover, the mesh-objectivity of the numerical solutions is ensured by resorting to a nonlocal regularization technique, based on the adoption of damage variables driven by an averaged elastic strain tensor. To perform the averaging of the strain tensor, an internal length lRG is considered in the continuum. The strategy chosen to define the parameters affecting the softening behaviour consists in the modification of the local softening law on the base of the internal length, with the intent of ensuring the proper evaluation of the correct fracture energy Gf. The adequacy of the proposed constitutive model in reproducing experimental results is proven for both monotonic and cyclic loading conditions. Under monotonic loads, unreinforced concrete notched elements subjected to pure tension, pure bending and mixed-mode bending are studied. The two examples of application involving cyclic loads, a masonry and a reinforced concrete wall under in-plane cyclic shear, constitute a validation of the multidirectional damage approach, showing how the suitable representation of unilateral effects and permanent deformations is essential to model the observed structural response in terms of maximum resistance and dissipation capacity. The effectiveness of the regularized damage formulation is proven by successfully studying a masonry arch and reinforced and unreinforced concrete elements. Besides the validation of the numerical results with experimental or analytical data, each application is exploited to highlight one or more features of the formulation: the mesh-size and mesh-bias independence of the results, the effect of the choice of the variable to be averaged, the possibility to reproduce structural size effects, the influence of the internal length lRG. On this latter aspect, the almost null dependence of the regularized solutions on the internal length in terms of force-displacement curves, achieved thanks to the calibration strategy adopted to define the energy dissipation, suggests the interpretation of the internal length as a regularization parameter. On the one hand, this implies an analogy between the role played by the nonlocal internal length in a nonlocal model and the one’s of the mesh size in the crack band approach (Bažant and Oh, 1983). On the other hand, this translates in the versatility of the regularized damage model, which requires only the identification of the standard material properties (elastic constants, fracture energies and strengths). Finally, the d+/d− damage model is successfully applied to the study of a three-span masonry arch bridge subjected to a concentrated vertical load, in order to evaluate its carrying capacity and its failure mechanism. Numerical issues, usually neglected in large-scale applications, are also addressed proving the reliability of the regularized approach to provide mesh-independent results and its applicability.

Abstract:
This investigation is aimed to present a simple analytical approach for predicting the ultimate strength of concrete arch using theory of plasticity. Six models of two-hinged parabolic concrete arches with and without steel reinforcement were tested under concentrated load. The observed behavior of cracking strength and collapse load of the arches tested were compared with those predicted by the analytical procedure proposed here. The arches tested were un-reinforced concrete, lightly reinforced concrete, and concrete with filing iron respectively. A Good agreement is found between the proposed analysis and test results. Tests have shown that the collapse of all arches was mainly due to the formation of two plastic hinges at a point of maximum bending moment which is similar to collapse mechanism adopted in this study. The use of light concentric steel reinforcement resulted into a significant increase in the ultimate load. This increase reaches up to three times of that without reinforcement. Ductility was also found to be greatly improved due to using steel reinforcement in arches. The procedure of analysis in this paper can give a simple guide for design of concrete arch.

Abstract:
<p>Design and construction of a triple-span precast concrete open spandrel arch bridge over a river for an integrated commercial and residential development project is presented. Due to the bridge skew angle and necessity for the newly constructed bridge to serve as one of the landmark along the river for this project, a triple-span precast arch bridge with open-spandrel concept was designed with special consideration to aspect of speedy construction. Precast construction technique was adopted with three main precast concrete components, namely open-spandrel supporting arch frame, tie beam and plank for composite slab. Arch span of 19m with rise of 4.25m, and arch span of 25.0m with rise of 5.0m were designed respectively for two side spans and middle span of the bridge. The main supporting arch component was made of two units of half arches joined at the crown with a specially designed joint. Besides the traffic loading, the design of these supporting arches was carried out taking into account aspect of transportation of the precast unit to site and also aspect of ease of erection at site. After the two supporting arch units and tie-beams were launched using cranes, special joint at the crown was cast to form a rigid arch frame. The construction process of the precast arch bridge with minimal number of joints connecting specially designed precast units meet the construction time frame and budget set by the client.</p>

Abstract:
This study details a multiprong effort to validate the Cold Regions Research and Engineering Laboratory’s solution for concrete construction and repair in cold weather, Additive Regulated Concrete for Thermally Extreme Conditions (ARCTEC). ARCTEC is the product of several years of research and consists of a testing and simulation workflow which generates scenario-sensitive guidance for use of accelerating admixtures in concrete. This report details efforts to validate ARCTEC using real-world, full-scale, field demonstrations. These demonstrations were used to collect data on the behavior of concrete obtained through conventional supply chains, to assess the accuracy of the simulation component of the workflow, and test efficacy of ARCTEC guidance in achieving frost protection. Results indicate that ARCTEC is at a high level of maturity, and provides additive dosage guidance that ensures frost protection and strength development in concrete placed where overnight lows fall as low as 0°F. The effort and cost required to implement ARCTEC as a cold weather protection strategy is minimal, and significantly less burdensome than conventional methods. Any cold region installation with a winter construction or repair needs and access to conventional concrete supply chains could field ARCTEC, and reduce the cost and schedule constraints associated with winter construction.

Pacific Earthquake Engineering Research Center, University of California, Berkeley, CA, March 2019. http://dx.doi.org/10.55461/crjy2161.

Abstract:
Evaluating the seismic performance of concrete dams requires nonlinear dynamic analysis of two- or three-dimensional dam–water–foundation rock systems that include all the factors known to be significant in the earthquake response of dams. Such analyses are greatly complicated by interaction between the structure, the impounded reservoir and the deformable foundation rock that supports it, and the fact that the fluid and foundation domains extend to large distances. Presented in this report is the development of a direct finite-element (FE) method for nonlinear earthquake analysis of two- and three-dimensional dam–water–foundation rock systems. The analysis procedure applies standard viscous-damper absorbing boundaries to model the semi-unbounded fluid and foundation domains, and specifies at these boundaries effective earthquake forces determined from a ground motion defined at a control point on the ground surface. This report is organized in three parts, with a common notation list, references, and appendices at the end of the report. Part I develops the direct FE method for 2D dam–water–foundation rock systems. The underlying analytical framework of treating dam–water–foundation rock interaction as a scattering problem, wherein the dam perturbs an assumed "free-field" state of the system, is presented, and by applying these concepts to a bounded FE model with viscous-damper boundaries to truncate the semi-unbounded domains, the analysis procedure is derived. Step-by-step procedures for computing effective earthquake forces from analysis of two 1D free-field systems are presented, and the procedure is validated by computing frequency response functions and transient response of an idealized dam–water–foundation rock system and comparing against independent benchmark results. This direct FE method is generalized to 3D systems in Part II of this report. While the fundamental concepts of treating interaction as a scattering problem are similar for 2D and 3D systems, the derivation and implementation of the method for 3D systems is much more involved. Effective earthquake forces must now be computed by analyzing a set of 1D and 2D systems derived from the boundaries of the free-field systems, which requires extensive book-keeping and data transfer for large 3D models. To reduce these requirements and facilitate implementation of the direct FE method for 3D systems, convenient simplifications of the procedure are proposed and their effectiveness demonstrated. Part III of the report proposes to use the direct FE method for conducting the large number of nonlinear response history analyses (RHAs) required for performance-based earthquake engineering (PBEE) of concrete dams, and discusses practical modeling considerations for two of the most influential aspects of these analyses: nonlinear mechanisms and energy dissipation (damping). The findings have broad implications for modeling of energy dissipation and calibration of damping values for concrete dam analyses. At the end of Part III, the direct FE method is implemented with a commercial FE program and used to compute the nonlinear response of an actual arch dam. These nonlinear results, although limited in their scope, demonstrate the capabilities and effectiveness of the direct FE method to compute the types of nonlinear engineering response quantities required for PBEE of concrete dams.

Abstract:
The design of buried pipes, in terms of the allowable minimum and maximum cover heights, requires the use of both geotechnical and structural design procedures. The geotechnical procedure focuses on estimating the load on the pipe and the compressibility of the foundation soil. The focus of the structural design is choosing the correct cross-section details of the pipe under consideration. The uncertainties of the input parameters and installation procedures are significant. Because of that, the Load Resistance Factor Design (LRFD) method is considered to be suitable for the design of buried pipes. Furthermore, the interaction between the pipe structure and surrounding soil is better captured by implementing soil-structure interaction in a finite element numerical solution technique. The minimum cover height is highly dependent on the anticipated traffic load, whereas the maximum cover height is controlled by the section properties of the pipe and the installation type. The project focuses on the determination of the maximum cover heights for lock-seam CSP, HDPE, PVC, polypropylene, spiral bound steel, aluminum alloy, steel pipe lock seam and riveted, steel pipe and aluminum arch lock seam and riveted, non-reinforced concrete, ribbed and smooth wall polyethylene, smooth wall PVC, vitrified clay, structural plate steel or aluminum alloy pipe, and structural plate pipe arch steel, or aluminum alloy pipes. The calculations are done with the software CANDE, a 2D plane strain FEM code that is well-accepted for designing and analyzing buried pipes, that employs the LRFD method. Plane strain and beam elements are used for the soil and pipe, respectively, while interface elements are placed at the contact between the pipe and the surrounding soil. The Duncan-Selig model is employed for the soil, while the pipe is assumed to be elastic. Results of the numerical simulations for the maximum fill for each type and size of pipe are included in the form of tables and figures.
