The effect of coupled beam models in buildings where earthquake loads are fully resisted by r/c shear walls on structural performance

Abstract

Reinforced concrete shear walls around the stairs and elevator shafts, which are at the core of the structures where earthquake loads are fully resisted R/C shear walls, are generally connected to each other with coupling beams. The aim of this study is to examine the effects of different reinforced concrete coupling beam types and analysis models whose earthquake loads are fully resisted by R/C shear walls on the performance of the building. In this study, nonlinear pushover analysis was performed for each R/C coupling beam model according to the ground acceleration of the Istanbul Ataturk Airport region according to the Turkish Building Earthquake Code (2018) of the 16-storey building model, which uses fully shear walls as vertical carrier. When the analysis results are examined, it has been seen that different reinforced concrete coupling beam types have serious effects on structural performance targets. © 2021, TUBITAK.
