Dolgu duvarlarin betonarme taşiyici sistem performansina etkisinin belirlenmesi

In this study, the effect of infill walls on the structural performance of reinforced concrete (RC) buildings with distortional irregularity under earthquake excitation was studied. With the aim to examine this effect, RC buildings with infill walls of 5 and 7 floors were modeled by using SAP2000 analysis program and pushover analyses, which is one of the nonlinear static procedures proposed in the Turkish Seismic Code (TSC, 2007), were conducted. At the phase of adding infill walls to the system, material characteristics given by TSC 2007 were used and the method of equivalent compression strut model, which is a widely accepted method, was used. According to the results, it is observed that more damage occurs in the models without infill walls. The columns located in the significant damage state were shifted into the minimum damage state with the inclusion of infill walls, whereas the beams in the heavy damage state remained in the significant damage state in the models with infill walls. As a consequence, RC buildings that do not satisfy life safety performance level satisfied life safety performance level when the contribution provided by infill walls against lateral loads is taken into account.
