Abstract

Interactions between
inadequately separated neighboring buildings have been repeatedly observed
during earthquakes. These interactions may result in substantial damage or even
total destruction of colliding structures during strong ground motions. This
study focuses on investigation of pounding response between RC buildings with
equal heights and different dynamic characteristics considering Seismic Zone 1
of Turkey. A collision between buildings is represented by a pounding model
commonly used in the literature, which is a nonlinear elastic spring (Hertz
model). In this study, the considered ground motion records are scaled
according to design spectrum given for Seismic Zone 1 in Turkish Earthquake
Code 2007 (TEC–2007). Neighboring buildings are modelled as a three-dimensional
beam-column system which is a widely constructed building type in Turkey.
Pounding analyses of the neighboring buildings are performed in time domain by
aid of SAP2000 program. Pounding forces obtained from the analyses are used to
investigate the pounding response between buildings RC buildings with equal
heights and different dynamic characteristics considering Seismic Zone 1 of
Turkey. The results presented in this study represents that gap values defined
in TEC–2007 are insufficient.

1. Derece Deprem Bölgesinde, Aynı Yüksekliklere ve Farklı Dinamik Özelliklere Sahip Betonarme Binalar Arasındaki Çarpışma Davranışı

Abstract

Son
meydana gelen depremlerde, aralarında yetersiz derz boşlukları bulunan komşu
binaların birbirlerinden etkilendikleri gözlemlenmiştir. Bu etkileşim, çarpışan
binaların büyük depremler sırasında ciddi zarar görmelerine veya tamamen
yıkılmalarına sebep olabilir. Bu çalışmada, Türkiye’nin birinci deprem
bölgesinde, eşit yüksekliklere ve farklı dinamik karakteristiklere sahip komşu
betonarme binaların çarpışma davranışları incelenmiştir. Binalar arasındaki
çarpışma, literatürde sıkça kullanılan lineer olmayan elastik yay (Hertz
modeli) çarpışma modeli ile temsil edilmiştir. Bu çalışmada, ivme kayıtları Türk
Deprem Yönetmeliğinde (TDY–2007)
birinci derece deprem bölgesi için verilen tasarım spektrumuna göre
ölçeklendirilmiştir. Komşu binalar, Türkiye’de çok sık kullanılan üç boyutlu
kolon kiriş sistemi olarak modellenmiştir. Komşu binaların çarpışma analizleri SAP2000
program kullanılarak zaman tanım alanında analiz yöntemiyle
gerçekleştirilmiştir. Birinci derece deprem bölgesinde, eşit yüksekliklere ve
farklı dinamik karakteristiklere sahip komşu betonarme binaların çarpışma
analizleri neticesinde çarpışma kuvvetleri elde edilmiştir. Bu çalışmanın
sonucunda, TDY–2007’de
tanımlanan derz miktarlarının yetersiz olduğu anlaşılmıştır.
