“…Yönetmeliklerde sıklıkla üstünde durulan çapraz donatılı bağ kirişlerine alternatif olarak, Şekil 7'deki gibi çift kiriş oluşturacak şekilde, donatıların ayrı ayrı etriyelerle sarıldığı çalışmalara da literatürde rastlamak mümkündür [11].…”

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.

“…The paper of Xue et al (2018) showed that SRC frame with irregular section columns is suitable for the construction in the high seismic intensity zone. Choi et al (2018) pointed out that the lower angles of inclination for the diagonal reinforcement, when accorded to the detailing requirements specified in ACI 318 (2014), result in reinforcement congestion and construction difficulties. The existence of both rebar cages and reinforcing steel causes the conflict between rebar cages and reinforcing steel in space (Ye et al, 2013).…”

The interface slip between shape steel and concrete is one of the biggest problems in numerical simulation of composite structures, this paper aims to investigate interfacial bond-slip behavior between steel and steel fiber reinforced concrete. For this purpose, a series of push-out tests on 15 circular section specimens which were designed and fabricated with different steel fiber ratio, interface embedded length and concrete cover thickness have been done. Experimental results show that average bond strength versus free end slip curves of each specimen is similar, and then a basic average bond strength-free end slip constitutive model was proposed in this paper. Meanwhile, considering the distribution regularities of steel strains, local bond strength and relative slip along the interface embedded length at different load levels were obtained through the mechanical derivation, the results show that the maximum local bond strength was located near the free end, and the local bond strength away from free end tended to be steady. Based on the basic average bond strength-free end slip constitutive model, two position functions were proposed to describe the local bond-slip constitutive model considering the variation of positions. Two position functions are of great significance for further research on SSFRC non-linear properties by FEM.

“…Several experimental studies investigated the coupled shear wall system in terms of the reinforcement layout for the coupling beams [8,22,23]. In terms of the numerical modeling of CBs, a number of studies over the previous decades have been conducted with CB's modeled as an equivalent continuous shear medium (e.g.…”

Modern construction of high-rise and tall buildings depends on coupled shear walls system to resist the lateral loads induced by wind and earthquake hazards. The lateral behavior of this system depends on the structural behavior of its components including coupling beams and shear walls. Although many research studies in the literature investigated coupling beams and shear walls, these studies stopped short of investigating the coupled shear walls as a system. Therefore, in this research, the effect of the coupling beam parameters on the nonlinear behavior of the coupled shear walls system was investigated. The full behavior of a 10-story coupled shear wall system was modeled using a series of finite element analyses. The analysis comprised of testing several coupling beam parameters to capture the effect of each parameter on system response including load-deflection behavior, coupling ratio, crack pattern, and failure mechanism. The results indicated that a span-to-depth ratio equal to two is a turning point for the coupling beam behavior. Specifically, the behavior is dominated by ordinary flexure for a ratio of more than two and deep beam behavior for a ratio of less than two. This study showed that the coupling beam width does not have a significant effect on the coupled shear wall response. Additionally, it was concluded that the excessive coupling beam diagonal reinforcement could significantly affect the coupled shear walls behavior and therefore an upper limit for the diagonal reinforcement was provided. Moreover, limitations on the longitudinal and diagonal reinforcement and stirrups are presented herein. The analysis results presented in this paper can provide guidance for practitioners in terms of making decisions about the coupling ratio of the coupled shear walls.
