Burulma düzensizliğine sahip betonarme çerçeveli taşiyici sistemlerin performansina dolgu duvarlarin etkisinin belirlenmesi

In this study, the effect of infill walls on the structural performance of reinforced concrete (RC) buildings with torsional irregularities under earthquake excitation has been studied. With the aim to determine this effect, RC buildings of 5 and 7 floors with and without infill walls were modeled by using SAP2000 analysis program and their pushover curves have been obtained by the nonlinear static procedure "Incremental Equivalent Seismic Load Method (AEDYY)" and the linear static procedure "Equivalent Seismic Load Method (EDYY)" which are proposed by the Turkish Seismic Code (TSC, 2007). Infill walls have been modeled by using the method of equivalent compression strut model and material characteristics given in the TSC 2007. According to the results, more damage has been determined to occur in models without infill walls. Columns located in significant damage state have transited to the minimum damage state with the inclusion of infill walls. On the other hand, beams in heavy damage state have remained in significant damage state even in the models with infill walls. As a consequence, RC buildings that do not satisfy life safety performance level have satisfied life safety performance level when the contribution made to the building by infill walls against lateral loads is taken to account.
