Abstract

Bu çalışmada, yumuşak kat düzensizliğine sahip betonarme yapıların sismik yükler altındaki hasar görebilirlikleri Artımsal Dinamik Analiz (IDA) yöntemi kullanılarak değerlendirilmiştir. Çalışma kapsamında, farklı zemin kat yüksekliği ve dolgu duvar düzenine sahip altı farklı yapı modeli oluşturulmuş ve her bir yapı, çeşitli ölçeklenmiş yer hareketlerine maruz bırakılarak yapısal tepkileri analiz edilmiştir. Analizlerde hasar ölçütü olarak göreli kat ötelenmesi, şiddet ölçütü olarak ise En Büyük Yer İvmesi (PGA) kullanılmıştır. Elde edilen IDA eğrileri doğrultusunda, her bir model için OP, IO, DC, LS ve CP performans seviyelerine karşılık gelen kırılganlık eğrileri türetilmiştir. Sonuçlar, zemin katta dolgu duvar eksikliği ve kat yüksekliği artışının yapının yatay rijitliğini azalttığını, bu durumun ise kırılganlığı önemli ölçüde artırarak daha düşük PGA seviyelerinde yüksek hasar olasılıklarına yol açtığını ortaya koymuştur. Bu bulgular, yapı tasarımında geometrik ve dayanım yönünden sürekliliğin önemine dikkat çekmektedir.
