The shear strength of concrete, while not being an independently standardized indicator of concrete quality, plays an important role in the analysis of reinforced concrete structures. The concepts related to the dependence of the shear strength of concrete on the standardized compressive and axial tensile strength are quite ambiguous. Self-compacting concrete (SCC), which has been widely used recently, is somewhat different from ordinary concrete (OC) compacted by vibration in terms of structure and properties, and data on the shear strength of SCC are sparse. Purpose of the study: We aimed to clarify the dependence of the shear strength of concrete on the standardized compressive and axial tensile strength, and assess the shear strength of SCC in comparison with that of OC. Methods: We compared the shear strength of SCC with that of OC experimentally, by applying the common methodology with the use of a Mörsch specimen and performing modeling in MATLAB with the use of six strength theories. Results: No significant differences were found in the dependence of the shear strength of SCC in comparison with that of OC at the design age of 28 days. In terms of quantity, the excess of the shear strength of SCC relative to OC is less than 12%. The best agreement with the experimental data among those analyzed is provided by the Geniev theory. The shear strength of concretes is most likely described by the equation Rsh=k*(R*Rt)^(1/2) at k = 0.5–0.6.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42690706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The circle represents vitality or energy, while the square represents strength. In world history, the concept of geometry traces its origins to construction in Egypt and Babylonia, where proportional systems were described through mathematical equations. They later became known as the Pythagorean Theorem, named after Pythagoras. In Ancient India, the concept of geometry starts with the construction of altars for Vedic sacrifices, as per the instructions of the Śulbasūtras. This involved creating circles and squares, converting squares to circles and vice versa, resulting in altars of various shapes and proportionate systems. The intersection of these basic shapes, the square and the circle, is the key to constructional building geometry. For instance, Vesica Piscis is a geometrical element derived from the circle-circle intersection. It has been applied by researchers to examine the geometry of both ancient and modern buildings. Similarly, the Square-Circle Sequence (SCS) is a method derived from the square-circle intersection. Gandotra (2011) used it to study the constructional geometry of the Hindu temples in North India (Nāgara temples). Meister (1985) also applied the square-circle intersection geometric constructional method to define the proportionate system of the Hindu temples in India. Finally, this study attempts to correlate these types of constructional geometry in the evolution of elevational form of Nāgara temples through Lakshman temple in Sirpur. It determines that the building’s elevational form may be derived from the basic shapes of the circle and the square.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42559830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the versatility of existing mold systems in construction, shell-type roofing structures are entirely different from other structural elements widely used in construction practice in terms of their outline and overall dimensions. Therefore, to erect them, it is necessary to build an individual mold system, which would provide the appropriate spatial shape for cast-in-situ reinforced concrete roofing. Due to the scale of shell roofs, the installation of such mold systems is often associated with significant difficulties as it requires a large, bulky structure above the ground surface with the use of load-bearing scaffolding and planking. This results in issues of building individual elements and the entire mold system and accurately placing them in the design position, which can be solved quite easily using the experience gained from similar works. As a demonstration of this, an example of the arched roof construction for the church named after the Mother of God of Iveria, the second largest church in Georgia, was given a few years ago. At the time, the main difficulty was manufacturing and installing wooden arch molds, which was quickly overcome due to considering several practical measures in advance.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42511634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many countries worldwide have witnessed increased demand for residential buildings due to population growth. However, because of the economic conditions that most countries suffer from, the search for low-cost housing without compromising the quality of construction and materials has become extremely essential. Low-cost construction meets the demand for cost-effective design solutions without prejudice to quality. Purpose of the study: We aimed to determine the applicability of building materials and technologies used in low-cost construction. Methods: In the course of the study, we thoroughly reviewed literature sources addressing low-cost construction. Results: Based on the review, we determined six strategies of low-cost construction: effective planning, use of low-cost materials, use of environmentally-friendly materials, use of cost-efficient construction techniques, use of available alternative construction methods, and sustainable community through involvement and training. All over the world, knowledge exchange and technology development within local societies are considered techniques that reduce the cost of buildings at the expense of local manpower. We recommend governments to enhance the involvement of local resources by developing training programs in cooperation with local communities. Besides, governments should provide opportunities for the application of environmentally-friendly construction materials and encourage their use. This study will help researchers delve deeper into the issues and obstacles occurring in low-cost construction.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44748087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the technologies providing high efficiency and reducing resource consumption in combination with reagent methods, hydrodynamic cavitation water treatment is of particular interest. The analysis of scientific and technical data made it possible to determine the main indicators of hydrodynamic cavitation water treatment that can affect the efficiency of reagent purification. Extreme parameters occurring during intense cavitation are associated with the formation of high temperatures up to 2000°C and high pulse pressures of 100–1500 MPa in local areas of hydrodynamic systems. In such conditions, the initiation and intensification of the physical and chemical processes of water treatment are observed. Рurpose of the study: Improving the efficiency of existing traditional water purification technologies, allowing to improve its quality at the lowest cost. Methods: To study the parameters affecting water treatment efficiency and occurring with the cavitation flow of water, simulation in Ansys CFX was performed with the use of the finite volume method. The calculation was carried out with account for the turbulent nature of the flow based on the k-ε turbulence model. The cavitation process was calculated with the use of the Rayleigh-Plesset cavitation model. Results: Steam formation in the cavitation reactor promotes sufficiently complete absorption of the gaseous disinfectant by water. An increase in temperature is also considered as one of the factors increasing the efficiency of water treatment with reagents. During cavitation, water temperature increases in local micro-volumes. Thus, to intensify the process, there is no need to heat the entire volume of liquid, and, as a result, the total energy consumption for water treatment is reduced.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45281333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this paper is to investigate the effectiveness of wire mesh in the retrofitting of flexural members such as reinforced concrete beams. It also investigated the flexural capacity of the beams, which are reinforced with wire mesh as a partial or complete replacement of regular rebar. The orientations and various forms of the wire mesh within the beam section are taken into consideration. The finite element method is used to model and analyze the beams. The structural performance of the studied beams, including the load-deflection relationship, first cracked and ultimate cracked loads, crack patterns, and flexural stress, were evaluated using the finite element method. The finite element model of the beam which is reinforced with wire mesh has been verified with experimental results. The results show that beams retrofitted with ferrocement or beams in which rebar is replaced by wire mesh have superior flexural performance and low crack depth. The beams retrofitted with wire mesh have a high ultimate load-carrying capacity and ductility. The confinement of three-sided wire mesh improves the flexural performance of the beam. It is observed that flexural performance remains the same when the length of the wire mesh exceeds half of the span length.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49151010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose of the study: We aimed to integrate computational design technologies to create self-learning buildings that could adapt to environmental challenges and adjust accordingly by collecting data from the surrounding environment via the implementation of sensors. Methods: We started with extensive research on state-of-the-art computational design in architecture, followed by the design implementation and the implementation of the architectural design of a building. The design followed a parametric approach to design and strategies. An algorithm was developed with Grasshopper Scripting to generate documents that mimic the growth process of cellular bone structures and adapt that form to a selected project site. To ensure that the generated form is adaptable, we performed multiple analyses, such as sunlight, radiation, and shadow analysis, before selecting the form and finishing its development.
