FARKLI BETONARME BAĞ KİRİŞİ MODELLERİNİN TBDY (2018)’E GÖRE YAPI PERFORMANSINA ETKİSİ

Abstract

Boşluklu perdeli sistemlerin kullanıldığı betonarme yapılarda, bağ kirişleri yapı performansının belirlenmesinde ciddi rol oynamaktadır. Bu çalışmanın amacı, boşluklu perdelerin kullanıldığı yapı modellerinde kullanılan farklı betonarme bağ kirişi tiplerini, Türkiye Bina Deprem Yönetmeliği 2018’e (TBDY, 2018) göre yapılan doğrusal olmayan analiz sonuçlarına göre karşılaştırıp, sonuçlarının incelenmesidir. Çalışmada 19 katlı kolon-kiriş çerçeve sisteminin, boşluklu perdelerle bir arada kullanıldığı bina modeli, TBDY (2018)’e göre, İstanbul Atatürk Havaalanı bölgesinin yer ivmesine göre her bir betonarme bağ kirişi modeli için ayrı ayrı analiz edilmiştir. Yapılan analiz sonuçlarında farklı betonarme bağ kirişi tiplerinin yapının performans noktasında ve performans hedeflerinde ciddi etkilerinin olduğu görülmüştür.

The Effect of Different Concrete Coupled Beam Models on Structural Performance According to TBEC (2018)

Abstract

Coupling beams have a significant role in determining structure performance in reinforced concrete structures where coupled structural shear wall systems are used. The purpose of this study is to compare the different types of reinforced concrete coupling beams used in coupled structural shear walls models with the results of nonlinear analysis according to Turkish Building Earthquake Code 2018 (TBEC, 2018). According to TBEC (2018), the building model in which the 19 floor buildings in which seismic loads are jointly resisted by frames and coupled structural shear walls was analyzed separately for each reinforced concrete coupling beam model based on the ground acceleration of the Istanbul Atatürk Airport region. The results of the analysis showed that different types of reinforced concrete coupling beams have serious effects on the performance point and performance targets of the structure.
