Betonarme Yapı Elemanları için Güvenilirliğe Dayalı Yeni Yük ve Dayanım Katsayılarının Belirlenmesi

Bu calismada, yasanan buyuk depremlerden sonra Turkiye’de degisen tasarim ve uygulama kosullarina dayali olarak, betonarme yapi elemanlari icin yeni yuk ve dayanim katsayilari belirleme yontemi sunulmustur. Yontemin uygulamasi kesme gocme modundaki kirislere etkiyen sabit ve hareketli yuk kombinasyonu icin gerceklestirilmistir. Ilk once guvenilirlik analizi yapmak icin elde edilen veriler goz onunde bulundurularak, tasarim degiskenlerinin sahip oldugu belirsizlikler istatistiksel parametreler ile sayisallastirilmistir. Daha sonra, tasarim kosullarina dayali risk duzeyleri guvenilirlik indeksi, β, cinsinden hesaplanmistir. Hesaplanan bu β degerleri goz onunde tutularak hedef guvenilirlik indeksi, βT, uygun bir sekilde secilmistir. Son olarak, secilen guvenilirlik indeksi kullanilarak yuk ve dayanim katsayilari Gelistirilmis Birinci Mertebe Ikinci Moment yontemine gore hesaplanmistir
