In Turkey, heat loss from existing and new buildings constitutes a large part of energy waste, so usage of suitable construction material is quite important. The building selected in this study was analyzed by applying different building materials considering the annual energy consumption allowed, and according to the different heat zones and different thicknesses of insulation material in relation to demand. The most suitable building material in terms of energy and cost uptake and cost given to the regions was determined; the results were measured in the study in terms of the maximum allowable annual heating energy requirement and the optimum values were determined. Comparison of the optimum values and the total energy consumption rates was conducted for the analyzed cities.
KEYWORDSPeriod; In ll wall thickness; In ll wall elasticity modulus; RC structures; Modal analysis.Abstract. Estimation of a proper fundamental vibration period is an important issue in the process of the design and/or evaluation of a building. Mostly, in ll walls are assumed nonstructural elements which are ignored in the estimation of the vibration period of a building in terms of sti ness. However, studies showed that in ll wall has signi cant e ect on vibration period and should be considered in the estimation of period. Even in ll walls are considered by some proposed equations in the estimation of period, they do not consider the e ect of in ll wall sti ness. In this study, an empirical equation is proposed as a function of building height, elasticity modulus of in ll wall, and thickness of in ll wall. For this purpose, building periods were determined with considering di erent in ll wall elasticity moduli, in ll wall thicknesses (thus, di erent in ll wall sti ness), and building heights. Nonlinear regression analyses were conducted with a comprehensive statistical study. E ect of elasticity modulus and thickness of in ll wall on vibration period was investigated. Finally, comparisons between the proposed equation of this study and those of previous studies were conducted.
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.
