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.

Abstract:

In structural design, the preliminary synthesis stage derives judgmental knowledge from engineering heuristic and experience which are usually expressed in symbolic form. On the other hand, detailed design involves extensive numerical processing. An integrated computer-aided design system should be able to handle both symbolic and numerical processings. It must also be able to integrate engineering databases and CAD packages within a single environment. The knowledge-based system approach provides a venue for achieving all these requirements. This paper presents a prototype knowledge-based system for lattice design that can perform several essential tasks including preliminary synthesis, numerical model generation, nonlinear finite element analysis, code compliance checking and member sizing. The system user is guided throughout the design session by interactive graphical user interfaces which facilitate the design process.

Abstract:

The most important feature of architecture at Islamic age has been regarded as strengthening the human history from plurality and unity that such architecture from the artistic dimension and world structure goes beyond the time and place. Dome has been regarded as the major element in Islamic-Iranian architecture that there is no doubt on continuity and evolution of domical buildings since Sassanid age till current age. Mosques with Arabic or column design in Umayyad dynasty have been mentioned as the early styles in Islamic architecture. These mosques follow a square or rectangular map with walled garden and roofed nave. Since 7th century, domes have been the major element in Islamic architecture. By the passage of time, dimensions of domes at mosque developed, occupied a small part of the ceiling in proximity of Mihrab to the entire ceiling above nave. According to the existing texts, the oldest dome which is referred relates to Parthian and early Sassanid era. This dome has been built in Firuzabad to the dimension of 10.16 meter and evolved at Sassanid age, after which construction of domes is exploited as a general pattern. Domical buildings in west differ from domical buildings in Iran. Interesting difference lies on transfer of dome from cylindrical buildings to square buildings in Iranian architecture. Creation of dome and formation of hollow spaces have raised creation of spiritual spaces together with sense of comfort, under which the most important phenomenon of Islamic-Iranian architecture, holy shrines and sacred places have raised. In this research, firstly we will reach to a model of construction of main dome by overview of literature at architecture of domical buildings pre Islam in Iran and formation of them with an emphasis on domical buildings especially at Firuzabad, Fars and Bishapur, then we will review the domical buildings at Islamic age especially mosques and scared places, ultimately the evolution stages of dome design is examined in Islamic-Iranian architecture.

Abstract:

Double-layer tensegrity domes are formed from double-layer tensegrity grids (DLTGs) with cured surfaces. Typically such domes consist of truncated pyramidal units or their derivatives joined together. Unlike flat DLTGs, the geometric configuration of the dome involves shape finding. The initial, prestressed geometry depends on the constraints governing the construction of the dome. Both shape finding and load analysis involve geometric non-linearities, but the extent of nonlinear behaviour under load, i.e. the magnitude of deflections, depends on a number of factors. While tensegrity structures, like other prestressed cable networks, are often geometrically flexible, geometrically rigid configurations, involving only elastic deformations, are feasible.

Abstract:

This paper aims to provide an aerodynamic optimization procedure to improve the aerodynamic performance of single-layer spherical domes, by coupling the kriging surrogate model with computational fluid dynamics (CFD) and finite element analysis (FEA). Firstly, a series of wind tunnel tests on the mean pressures and wind-induced behavior of a single-layer spherical latticed shell, were carried out to investigate the effect of dome geometric parameters. Then, the Reynolds-averaged Navier-Stokes equations and RSM turbulence model were utilized for simulating the wind loads on spherical domes, and the numerical results are validated with experimental data. On this basis, the single-objective aerodynamic optimization of spherical domes based on ordinary kriging surrogates has been carried out to find out the optimal geometric parameters (rise/span and wall-height/span ratios). The objectives were minimizing the highest mean suction and the maximum vertical displacement, respectively. The optimization results showed that the optimal design of spherical domes exhibits a reasonable aerodynamic performance improvement compared with the near optimal solutions. In addition, the highest mean suction and the maximum vertical displacement can be reduced by decreasing the wall-height of the dome, and a good trade-off between the two objectives can be achieved by selecting suitable dome geometric parameters.

Braced domes may be fabricated in any of several common grid configurations. With different configurations, the dome performance varies considerably affecting both its competitiveness and suitability for specific applications. The study presented in this paper is an assessment of the most commonly adopted dome configurations and their effect on the dome characteristics such as the stiffness/weight value, member stress distribution, number of joints and members, degree of redundancy and cost. The study is parametric and covers wide variations of dome span/rise ratio and boundary conditions. The results of this study could be of significant value to the design of future braced dome structures.

Abstract:

AbstractSometimes scientific-technical objects can be given an extended meaning as cultural icons and be received in art and architecture. To this end, the object must be detached from its original context and viewed from different, new perspectives.In 1922 Walter Bauersfeld constructed one of the first geodesic domes for testing projection devices in Jena. Walter Gropius and Lázló Moholy-Nagy were among the first to visit the Jena Planetarium; Moholy-Nagy received the dome in his book ›Von Material zu Architektur‹. Richard Buckminster Fuller further developed Bauersfeld’s concept from the 1940s and patented the construction principle of a geodesic dome under the name ›Building Construction‹ in 1954. His patent bears resemblances to the Bauersfeld Planetarium in Jena, which can be demonstrated by manuscripts by Bauersfeld from the Zeiss Archive in Jena. Fuller, on the other hand, also used the geodesic dome to explain his theory as Synergetic. The article traces the transformation of the technical object conceived by Bauersfeld via Moholy-Nagy and Fuller into a cultural icon of the 20th century.

Abstract:

The interest in earthbag dome construction (also known as earthbag or superadobe) has been increasing as world consciousness develops to achieve the planet’s equilibrium for sustainable living. The main objective of this research is to develop a parametric tool to help architects modeling virtual earthbag domes from ideation to construction phase. This challenge has been addressed by adopting an experimental methodology that explores parametric generative design with the use of a visual programming language (VPL). In this paper we present the development of a tool for the ideation level including features that allow for the calculation of material quantification. Even thought, the tool does not work in a Building Information Modeling environment, the generative model outputs technical information to support construction, namely material quantities. The usability of the tool was validated by a random international sample of experts.

Abstract:

To create fundamentally new innovative large-span structures of buildings and structures coverings, modern design solutions of prestressed cable domes of the Tensegrity type are considered. The service life of the first built Tensigrity domes is only 35 years. These are fairly new, effective structures that require careful study and use of modern scientific approaches for their design using software systems, since their work under load and the construction process are quite complex. The design analysis and erection of self-stressed structures is based on the invention of an equilibrium structure, the so-called tensegrity form. The search for the shape is multidimensional and consists of the stage of computational analysis of a self-stressed dome for the equilibrium position of elements and their nodes, selection of the most stable and rigid structure, as well as taking into account possible unfavorable loads during operation and the initial load in the elements from the application of prestressing. To determine the shape of cable domes, a nonlinear programming problem with given axial forces is formulated, which can be considered as the problem of minimizing the difference in the total strain energy between the elements of the cables and struts under constraints on the compatibility conditions. The first step in calculating the prestressing of a cable dome is to assess the feasibility of its geometry. The possibility of forming a cable dome of negative Gaussian curvature is considered and a method for calculating the prestressing for this new shape is investigated. The proposed method is effective and accurate in determining the allowable prestressing for a cable dome with negative Gaussian curvature and can be used for other types of prestressed structures. The new directions for the development of effective constructive solutions for large-span coatings are presented, including a suspended-dome structure, which combines the advantages of a mesh shell and a cable dome. Special attention should be paid to experimental studies on models of tensegrity domes, the results of which demonstrate the positive and negative aspects of the behavior of structures under load, the process of their erection, as well as the possibility of control and restoration during operation.

The building production is affected by many factors. With some we can count, but we cannot predict some for certain in advance. The essential precondition for successful implementation of a construction is thorough and timely preparation of pre-production and production engineering (technology designing), which provides for the effective implementation of the works.

Abstract:

The paper presents the topological–geometric analysis of a selected number of space frames configurations for geodesic domes which are generated from the regular octahedron. Two subdivision methods for spherical triangles, proposed by Fuliński, were used to create two families of structures. The first family consists of six single-layer and six double-layer geodesic domes shaped on the basis of the first method of subdivision, while the second family contains six single-layer and six double-layer geodesic domes shaped on the basis of the second method of subdivision. The calculated results of the geometric parameters of the analyzed structures were used to create original formulas that allow for more advanced structures to be achieved, that is, with a larger number of nodes and struts. The geometric results were also used to create nomograms showing the range of struts of the same length for double-layer geodesic domes. In both single-layer and double-layer domes, the number of groups of struts of equal lengths and the number of faces with different areas are smaller for structures created according to the first method of subdivision. The comparison of the resulting element quantities of two methods shows that the largest differences appear between the domes with a larger number of struts (up to 67%). Here, the analysis might help the designer reach a final decision on the better choice of topology, in particular, when this aspect is combined with other design goals, such as efficiency, economy, utility, and elegance in the design of the structure and the cover of large areas.

Abstract:

Domes are efficient structural systems for long clear-span buildings. The introduction of laminated timber highlighted the economic advantages of this material and led to the use of timber domes even for very large spans. In this paper, reticulated timber domes of triangular network shape with decking and bottom tension ring are considered. These types of domes have high stiffness in all directions along the surface and are kinematically stable. The dome is subjected to uniformly distributed load over the entire structure. The dome model is generated with a preprocessor program called DOME-IN and analysed with ABAQUS. The focus of this paper is to evaluate the behaviour of reticulated timber domes with respect to different stiffnesses of the bottom ring beam, here defined as a non-dimensional ring beam area parameter Ar*, which is shown to be a very well adapted design parameter for the ring beam. As far as global buckling is concerned, the critical pressure is sensitive to the bottom ring beam stiffness only if the latter is within a certain range. In terms of design, the stiffness of the ring beam should exceed A* > 2 in order to utilise the full buckling load capacity of the dome system itself. The maximum deflection, normal forces and bending moments versus the ring beam area parameter are also evaluated. The maximum values of the deflection and the internal actions next to the bottom ring are very sensitive to the bottom ring beam stiffness only if the latter is less than about Ar* < 10. A recommended value for the design of the bottom ring beam is A* > 20.

Abstract:

The high-strength concrete is a cement composite reaching high compressive strength, namely, pursuant to the legislation, higher than 60 MPa in the terms of cube compressive strength. The development of high-strength concretes exceeding 100 MPa is still an up-to-date issue and the production of these concretes is still limited only to a prefabrication. Contemporary construction industry and projecting activity have begun to focus on a construction of statically demanding buildings, which can include e.g. high-rise buildings. Such projecting often requires using of the state-of-the-art materials like cement composites with high mechanical parameters for construction of more subtle buildings. Within this article, the procedure of ready-mixed concretes development with the compressive strength around 100 MPa designed according to a project documentation for actual construction of high-rise building with the height up to 160 meters and 46 floors is described, together with the influence of the aggregate on the resulting composite strength.

Abstract:

This paper discusses the conceptual design of decorative crystalline domed structures. The application of the structure itself as a decorative element in combination with three ways of shape-forming: spatial, structural and geometrical, is a feature of such composite shape formation of crystalline domed shells. The author developed a computer-aided design procedure for decorative means of forming crystalline dome-and-shell structures. The procedure can be applied to preliminary multiple-alternative geometrical modelling of ornamental-decorative constructural forming of networks as well as designing the decorative finish to domed shell surfaces.

Abstract:

Muqarnas is a three-dimensional Islamic architecture decoration conceived as a spatial arrangement of 3D shapes according to precise geometric rules. Muqarnas work can be performed on several types of materials such as stone, wood, plaster or brick. This paper aims to propose an algorithmic method to construct the circular Moroccan-Andalusian Muqarnas Ornaments from their 2D representation models. The principle is to extract from a 2D design geometric information and underlying rules useful for the construction of its corresponding 3D model. To do so, the first stage consists to determine for each 2D shape of the 2D design model its corresponding 3D Muqarnas element. The second stage consists to perform the spatial composition of these identified 3D elements by using their neighborhood properties. The performance of the proposed method is evaluated by its capacity to reconstruct historical circular Muqarnas ornaments appeared during the Almoravids (1040-1147) and Almohads periods (1147-1269). This performance is further evaluated by the ability of the proposed method to construct all possible variants of a historical 3D Muqarnas ornament by considering the different 3D shapes which can be associated to the same 2D shape.

Abstract:

Purpose This study evaluates the enablers and barriers for modular concrete construction in Lebanon. The purpose of this paper is to investigate various factors (time, cost, technical know-how, organizational, sustainability, etc.) and their influence on the choice of the construction method. The paper examines the different assessments of designers, manufacturers, and contractors regarding precast construction in comparison to traditional in-situ methods, and highlights the major differences in their views. Design/methodology/approach Structured face-to-face surveys were conducted with top management personnel of precast manufacturers, architectural and engineering firms, and contracting companies in Lebanon. In addition, a case study from the largest precast project in Lebanon was used to provide a deeper understanding of factors encouraging the use of precast concrete, and to highlight major onsite issues associated with its implementation. Findings On the one hand, the findings highlight technical, logistical, organizational, and cultural factors that inhibit the use of precast concrete as a construction method. On the other hand, results reveal that cost, time, sustainability, and flexibility factors are the main enablers for increasing the uptake of modular concrete construction. Originality/value The main contribution to knowledge is that this study presents different stakeholders’ perspectives on precast concrete construction. Moreover, this is the first research addressing precast concrete construction in the Middle East and Lebanon. The results of the study provide valuable global insights and recommendations that may help increase the uptake of precast concrete construction. They can also guide project stakeholders to properly match project characteristics and precast concrete as a construction method.

Abstract:

Abstract. Problem. World experience shows that high operational performance of road coverings in the conditions of intensive traffic with high speeds of motor transport and sharp braking are provided by introduction of cement concrete. One of the effective solutions for the construction of high-quality, dura-ble, economical pavements is the use of roller-compacted concrete - a no slump concrete with low water-cement ratio, that is placed by an asphalt pav-er similar to asphalt pavement construction. The design of quality mixtures of roller-compacted con-crete is based on performance, construction require-ments and economic efficiency. Goal. The purpose of the work is design the compositions of roller com-pacted concrete and investigation of their strength. Methodology. Roller compacted concrete samples were tested for compressive strength and tensile bending in accordance with DSTU B B.2.7-214:2009. Results. The four variants of mixtures are designed to select the optimal composition of roller compacted cement concrete. The first of one is based on the particle size distribution of aggregate grains in ac-cordance with DSTU B B.2.7-127:2015, the second variant shows the composition of normal-weight cement concrete class C25/30, the third variant is characterized by increased sand fraction and in the fourth composition fine fractions replaced with sand. Road rolled concrete С32/40 Bb b5.2 is designed. Originality. Roller compacted cement concrete for effective road construction technologies is designed, which allows to perform the installation of high per-formance cement-concrete pavement with the use of asphalt pavers and rollers and the possibility of rap-id commissioning of cement-concrete pavement. Practical value. Designed composition of roller compacted concrete with the use of local Ukrainian materials allow to ensure the construction of cost-effective, durable road pavement with the possibility to carry out the movement on the cement concrete pavement after 1-3 days.

Abstract:

The structural design process is iterative and involves many design parameters. Thus, this paper presents a controlled framework for selecting the adequate structural floor system for reinforced concrete buildings and efficiently utilizing the corresponding construction materials. Optimization was performed using an evolutionary algorithm to minimize the total construction cost, considering the costs of concrete, steel reinforcement, formwork, and labor. In the problem formulation, the characteristic compressive strength of concrete was treated as a design variable because it affects the mechanical performance of concrete. The design variables included the column spacings, concrete dimensions, and steel reinforcement of different structural components. The constraints reflected the Egyptian code of practice provisions. Because the choice of the structural floor system affects the design details, three systems were considered: solid slabs, flat slabs with drop panels, and flat slabs without drop panels. Two benchmark examples were presented, and the optimal design results of the structural floor systems were compared. The solid slab system had the lowest construction cost among the three structural floor systems. Comparative diagrams were developed to investigate the distribution of construction costs of each floor system. The results revealed that an adequate choice of design variables could save up to 17% of the building’s total construction cost.

Abstract:

Optimization is a widely used phenomenon in various problems and fields. Because time and resources are very limited in today's world, it can be said that the usage area of the optimization process will be expanded and spread in all areas of life. Although different methods are used in the realization of the optimization process, the performance of metaheuristic algorithms in solving problems has led to an increase in research on these methods. As in other fields, the application examples of these algorithms are diversifying and increasing in the field of structural engineering. In this study, the performance comparison of five different algorithms for the optimum design of an axisymmetric cylindrical wall with a dome is investigated. These algorithms are Jaya (JA), Flower pollination (FPA), teaching-learning-based optimization (TLBO) algorithms and two hybrid versions of these algorithms. ACI 318 regulation was used in reinforced concrete design with a flexibility method-based approach in the analyses. In the analyzes with five different situations of the wall height, some statistical values , and data of analysis numbers were obtained by running the algorithms a large number of times. According to the analysis results, Jaya algorithm is slightly better in terms of the speed of reaching the optimum result, but also all algorithms are quite effective and reliable in solving the problem.
