Mesnetlerinden Farklı Yer Hareketlerine Maruz Çok Katlı Çerçevelerin Deplasman Yüklemesine Göre Analizi
Abstract
Yapıların
sismik analizinde, genellikle tüm mesnetlere aynı deprem ivmesinin etki ettiği
kabul edilmektedir. Yapı temelinin rijit plakla teşkil edildiği durumlarda
gerçekçi olduğu bu yaklaşım, mesnetlerin birbirinden bağımsız hareket
edebilmesi durumunda deprem dalgası ilerleyişinin dinamik analize etkisini hesaba
katamamaktadır. Bu çalışmada deprem ivmesinin çalışmada mesnetlerinden farklı
yer hareketlerine maruz çok katlı çok açıklıklı çerçevelerin dinamik davranışı,
deprem yükünün yer deplasmanına bağlı olarak tanımlandığı deplasman yüklemesi
kullanılarak incelenmiştir. Farklı mesnet hareketlerine maruz yapıların modal
analiz prosedürü detaylı olarak anlatılmış ve yarı statik deplasmanların
yapının dinamik davranışına olan etkisi vurgulanmıştır. Deplasman yüklemesi ile
ortaya çıkan yüksek mod etkilerinin, az sayıda titreşim modu hesaba katılarak
elde edilmesi için bir statik düzeltme yöntemi verilmiş ve yöntemin geçerliliği
verilen bir sayısal örnekle gösterilmiştir.
