The purpose of this study is to investigate the seismic performance of a specific type structural system that is utilized for almost all of the new residential buildings currently constructed as part of the Istanbul Urban Transformation Project. The structural system under consideration is comprised of lateral and gravity system elements, namely columns and shear walls, that are connected by ribbed slabs and shallow flat beams placed within the slabs. Firstly, a representative building of the new stock of buildings is selected, and the structural members are proportioned and detailed according to the current Turkish structural and seismic codes. Then, the seismic performance of the building is investigated. The results handled in this study reveal that these type of buildings cannot satisfy the earthquake safety requirements defined in actual Turkish Seismic Code

İstanbul’un Kentsel Dönüşümü için Üretilen Binaların Deprem Güvenliklerinin Araştırılması

Öz

Bu çalışmada, İstanbul’da başlayan ve sürmekte olan kentsel dönüşüm projesi kapsamında inşa edilen konut türü binaların hemen hemen tümünde kullanılan taşıyıcı sistem modelinin deprem performansının araştırılması amaçlanmıştır. Bahsedilen taşıyıcı sistem modelinde, kolon ve perdelerden oluşan düşey ve yatay yük taşıyıcı elemanlar, dişli döşemeler ve bu döşemeler içinde teşkil edilen yassı kirişler ile birbirine bağlanmaktadır. Bu tür binaları temsil edecek şekilde seçilmiş orta yükseklikte bir betonarme bina güncel yönetmeliklere göre boyutlandırılmıştır. Daha sonra bu binanın deprem performansı araştırılmıştır. Bu çalışmadan elde edilen sonuçlar bu tür binaların yeterli deprem güvenliğini sağlamadığı yönündedir
