It is known fact that
the earthquake occurred in two decades have been caused serious pecuniary loss
and spiritual damages in Turkey. Massive earthquakes revealed that the existing
building stocks in urban regions are significantly vulnerable to seismic
hazard. It is very important that earthquake safety of existing buildings
should be determined as soon as possible and that unsafe ones should be
strengthened. Investigations on the damaged buildings show that material
strengths are very important parameters on the building performance. This paper
aimed to determine the seismic safety of the buildings in risky regions in
terms of earthquake and to evaluate general situation. Therefore,120 existing
RC residential buildings are chosen from different cities to predict the
general trend on the seismicity of buildings. The available material qualities
are taken into account in the analyzes of the buildings. Analyzes were carried
out by increasing the material strengths and the effect of the material
strength on the earthquake performance was examined. Structural Analyzes
Program (SAP 2000) was used in modelling of buildings and to obtain seismic
performance of residential buildings. Nonlinear elastic procedures given in
Turkish Earthquake Code 2007 (TEC) were applied in the analyses of structural
systems.

Türkiye' de son yirmi
yıl içerisinde meydana gelen depremlerin neticesinde büyük maddi kayıplar ve
manevi zararlar meydana geldiği açık bir durumdur. Büyük depremler neticesinde
kentsel bölgelerdeki mevcut binaların deprem riskine karşı oldukça dayanıksız
olduğu ortaya çıkmıştır. Dolayısıyla, mevcut betonarme binaların deprem güvenliğinin
önceden belirlenmesi ve depreme karşı dayanıksız yapıların güçlendirilmesi
hayati önem taşımaktadır. Depremler sonucunda, binaların deprem
performanslarının zayıf olmasının en önemli etkenlerinden biri kullanılan beton
ve donatı çeliği dayanımlarının zayıf olmasından kaynaklanmaktadır. Bu
çalışmada, Türkiye' de deprem açısından riskli bölgelerdeki binaların deprem
güvenliği belirlenerek, genel durum değerlendirilmesi amaçlanmıştır. Bundan
dolayı, farklı şehirlerden toplam 120 adet mevcut betonarme binalar seçilerek
deprem performansları belirlenmiş ve binaların depremselliği hakkında genel bir
durum değerlendirilmesi yapılmıştır. Binaların analizlerinde mevcut malzeme
kaliteleri dikkate alınmıştır. Aynı zamanda malzeme dayanımları artırılarak
analizler gerçekleştirilmiş ve malzeme dayanımının deprem performansı
üzerindeki etkisi incelenmiştir. Binaların modellenmesinde ve performanslarının
belirlenmesinde SAP2000 (Structural Analyzes Program) bilgisayar programı
kullanılmıştır. Binaların analizlerinde, Deprem Bölgelerinde Yapılacak Binalar
Hakkında Yönetmelik (DBYBHY)' te belirtilen, mevcut binaların deprem
performansının belirlenmesinde önerilen elastik olmayan hesap yöntem esasları
dikkate alınmıştır.
