Abstract

In recent years, for the assessment or evaluation of the existing buildings under the seismic loads, the Nonlinear Static Procedure (NSP) based on pushover analysis has become extremely popular in structural earthquake engineering community. This study focuses on the seismic performance evaluation of the structures. This aim can be achieved by introducing nonlinear methods for designing, analyzing and checking the design of structures so that they meet the selected performance objectives. Analysis procedures are capable of predicting the demands-forces and deformations. Taking into account Turkish Earthquake Resistant Design Code ( TERDC 2007) for the construction, performance levels which are effective to determine the levels of performance criteria descriptions has been described. Four storied exiting school building is analysed by using SAP 2000 analysis program according to the TERDC 2007.

Betonarme okul binasının TDY 2007’ye göre nonlineer statik analizi

Abstract

Yapıların deprem performanslarının değerlendirilmesi için son yıllarda geliştirilmiş bulunan statik itme analizine
dayalı basitleştirilmiş nonlineer analiz yöntemleri, mühendislik uygulamalarında giderek daha yaygın olarak
kullanılmaktadır. Bu çalışmanın amacı, yapının dayanım ve deformasyon (şekil değiştirme) kapasitelerini belirleyerek
ilgili performans düzeylerindeki deprem istemleri ile karşılaştırmak suretiyle, yapının performansını
değerlendirmektir. TDY 2007 dikkate alınarak binalar için, performans seviyelerinin açıklamaları yapılmış ve bu
performans seviyelerinin belirlenmesinde etkili olan kriterler açıklanmıştır. SAP 2000 analiz programı yardımıyla 4
katlı mevcut bir okul binasının TDY 2007 göre analizi yapılmıştır.
