Abstract

Only the life safety and collapse prevention in general earthquake resistant design philosophy are explicitly prevented in seismic design codes. Results obtained from the recent studies have enabled some major changes in seismic design codes for the general EQ-RD philosophy to be accomplished and in evaluating the seismic performance of existing structures. Estimating the seismic demands at low performance levels requires the consideration of inelastic behavior of the structure. This paper is intended to compare nonlinear dynamic time history and pushover analyses results on 3-, 9-, and 20-story steel moment resisting frames. The results in this study show that prediction of damage in structures is hard to estimate by means of push-over analysis.

Özet

Genel depreme dayanıklı yapı tasarımı ilkelerinden özellikle can güvenliği ve yapının göçmesi, deprem yönetmeliklerinde açık bir şekilde önlenmiştir. Yapılan son çalışmalar neticesinde, genel depreme dayanıklı yapı tasarımı felsefesinin gerçekleştirilmesi ve mevcut binaların sismik performanslarının değerlendirilmesi konularında deprem yönetmeliklerinde önemli değişiklikler meydana gelmiştir. Düşük performans seviyelerinde sismik taleplerin tahmin edilebilmesi için yapının doğrusal olmayan davranışının göz önüne alınması gerekmektedir. Bu çalışmada 3-, 9-, ve 20-katlı çelik çerçevelerde doğrusal olmayan zaman artımı ve öteleme analizi sonuçlarının karşılaştırılması hedeflenmektedir. Bu çalışma sonucunda, yapılardaki hasarın öteleme analizi yardımıyla tahmin edilmesinin zor olduğu görülmüştür.
