Abstract
Deprem yüklerinin tamamının betonarme perde duvarlarla karşılandığı yapıların çekirdeğinde yer alan merdiven ve asansör boşluklarının çevresindeki perdeler genellikle birbirlerine bağ kirişleri ile bağlanmaktadır. Bu çalışmanın amacı, farklı betonarme bağ kirişi tiplerinin, deprem yüklerinin tamamının betonarme perde duvarlarla karşılandığı analiz modellerinin yapı performansına olan etkilerinin incelenmesidir. Bu çalışmada 16 katlı, düşey taşıyıcı olarak tamamen perdelerin kullanıldığı bina modelinin, Türkiye Bina Deprem Yönetmeliği (2018)’e göre, İstanbul Atatürk Havaalanı bölgesinin yer ivmesine göre her bir betonarme bağ kirişi modeli için doğrusal olmayan itme analizi yapılmıştır. Yapılan analiz sonuçları incelendiğinde farklı betonarme bağ kirişi tiplerinin yapı performans hedeflerinde ciddi etkilerinin olduğu görülmüştür.

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 coupled beams. The aim of this study is to examine the effects of different reinforced concrete coupled 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 coupled 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 coupled beam types have serious effects on structural performance targets.
