Studies carried out concerning the non-bearing partition wall systems used in buildings have increased in recent years. A very limited number of studies about the behaviour of gypsum wallboard systems under cyclic repeated loads have been found in the literature. An experimental study was carried out under earthquake loads to investigate the properties of gypsum wallboard systems, such as general load–displacement behaviour, stiffness, displacement ductility ratios and energy dissipation capacities. Ten different non-bearing wall specimens were produced. Four of these wall specimens consisted of different gypsum wallboard infill walls and the remaining six consisted of plastered and non-plastered infill wall specimens built with clay bricks, light concrete briquettes and aerated concrete blocks. As a result of this study, the performance levels and general behaviours of dry gypsum infill wall systems under the effect of horizontal cyclic reversible loading were determined by comparing with other infill wall systems. Although the initial stiffness and ultimate load capacity values of the dry gypsum infill wall systems were lower compared to a masonry infill wall and lightweight concrete brick walls, it was determined that they performed very successfully in terms of displacement ductility ratio and energy dissipation capacity.
Many earthquakes have occurred in Türkiye which is located in an active earthquake zone. A large number of casualties has been experienced in these earthquakes. After these natural disasters that left deep scars in the country, the reliability of existing building stock has been a subject of debate and has become one of the key matters that make up the agenda of the country. Investigations, researches and findings related to the existing building stock were published in various periods and aimed to increase the level of knowledge on the subject. As a result of the findings obtained from the studies, the severity of the current situation required many precautions to be taken. In this context, the necessity of determining how the structures will behave in a possible earthquake has emerged and this issue has been addressed for the first time in the Regulation on Buildings to be Built in Earthquake Zones (DBYBHY) published in 2007. Since DBYBHY takes both high cost and time to identify and evaluate risky buildings, the Law on Transformation of Areas under Disaster Risk with no 6306 was published in 2012 and the rules to be used during the determinations are determined in the annex of this law titled as Principles Regarding the Determination of Risky Structures. In this study, the actions to be done in risky building conversion processes are briefly mentioned and supports that citizens who want to carry out the process within the scope of the law can receive from the state are examined in detail. In addition, strengthening and re-building costs for the Sağlam Apartment in Ankara, demolished within the scope of these laws and principles were compared.
It is essential to determine the thermal conductivity and earthquake performances by developing earthquake‐resistant building systems that have high thermal insulation properties that will be economical for people considering the need for energy deficit and low‐cost earthquake‐resistant residences in the world. This study aims to evaluate the seismic performance of pre‐casted reinforced concrete shear wall systems with double layer high thermal resistance capability and compare to standard monolithic reinforced concrete shear wall systems with non‐high thermal resistance capability. The coating material used for thermal insulation was developed as an inorganic, economical, easily applicable, high‐fire resistance capable and not to cause the problems observed in the currently used products. In the research, new generation methods were used to reduce the unit weight of cement binder inorganic insulation material to low levels and provide high thermal resistance features. The seismic performance tests of the new double insulation layer, pre‐casted reinforced concrete shear wall system were realized. The seismic performance of conventional reinforced concrete shear walls was compared with the developed system by testing lateral reversed cyclic loading that simulates the earthquake.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
