INVESTIGATION OF THE EFFECT OF INCREASE OF GROUND FLOOR HEIGHT ON SOFT STORY IRREGULARITY IN REINFORCED CONCRETE BUILDINGS

Abstract

Most structural damages during earthquakes are caused by structural irregularities such as soft-story irregularities. Under earthquake loads, the durability of structures with soft story irregularities decreases significantly, leading to catastrophic damages. Evidence from past earthquakes shows that the development and implementation of design standards for the prevention of soft story irregularities is of critical importance. In this study, ground floor heights of ground + 3 storey residential reinforced concrete buildings are designed as 3 m, 3.5 m, 4 m, 4.5 m and 5 m. The other storey heights were kept constant and determined as 3 m in all analyses. The analyses were performed using SAP2000 finite element software and nonlinear static pushover analyses were applied. Within the scope of the study, the period values of the structures were evaluated by comparing the ground floor and peak displacements. In addition, the plastic hinges in the structures were analysed, damage zones were determined and the differences between the plastic hinges were compared in detail. In conclusion, the increase in ground floor height has significantly affected the natural vibration periods, horizontal displacements, and damage distribution of structures. As ground floor height increases, more pronounced horizontal displacements in the seismic behavior of structures and greater damage to ground floor columns have been observed.

Öz

Depremler sırasında meydana gelen yapı hasarlarının büyük bir bölümü, yumuşak kat düzensizliği gibi yapısal düzensizliklerden kaynaklanmaktadır. Deprem yükleri altında yumuşak kat düzensizliğine sahip yapıların dayanıklılığı önemli ölçüde azalarak yıkıcı hasarlara yol açmaktadır. Geçmiş depremlerden elde edilen bulgular, yumuşak kat düzensizliklerinin önlenmesine yönelik tasarım standartlarının geliştirilmesinin ve uygulanmasının kritik bir öneme sahip olduğunu göstermektedir. Bu çalışmada, zemin + 3 katlı konut tipi betonarme yapılar, zemin kat yüksekliği 3 m, 3.5 m, 4 m, 4.5 m ve 5 m olacak şekilde tasarlanmıştır. Diğer kat yükseklikleri ise tüm analizlerde sabit tutulmuş ve 3 m olarak belirlenmiştir. Analizler, SAP2000 sonlu elemanlar yazılımı kullanılarak gerçekleştirilmiş ve doğrusal olmayan statik itme analizleri uygulanmıştır. Çalışma kapsamında, yapıların periyot değerleri, zemin kat ve tepe deplasmanları karşılaştırılarak değerlendirilmiştir. Bunun yanı sıra, yapılarda oluşan plastik mafsallar incelenmiş, hasar bölgeleri belirlenmiş ve plastik mafsallar arasındaki farklılıklar detaylı bir şekilde kıyaslanmıştır. Sonuç olarak, zemin kat yüksekliğinin artışı, yapıların doğal titreşim periyotları, yatay deplasmanları ve hasar dağılımları üzerinde önemli bir etki yaratmıştır. Zemin kat yüksekliği arttıkça, yapıların deprem davranışında daha belirgin yatay yer değiştirmeler ve zemin kat kolonlarında daha fazla hasarların meydana geldiği gözlemlenmiştir.
