Yakın-fay yer hareketi etkisindeki kablo-destekli köprülerin asinkronize dinamik analizi
Öz: Bu çalışmada, deprem hareketi dalga yayılma hızının dikkate alındığı asinkronize yer hareketi etkisindeki merkez açıklık uzunlukları birbirine yakın olan eğik kablo askılı ve asma köprü sistemlerinin yakın fay ve uzak fay yer hareketi (1999 Chi-Chi depremi) etkisi altındaki yapısal tepkileri karşılaştırılmıştır. Japonya’da inşa edilen Tatara Köprüsü eğik kablo askılı köprü modeli olarak seçilirken, Türkiye’de inşa edilen Fatih Sultan Mehmet Köprüsü asma köprü modeli olarak tercih edilmiştir. Dikkate alınan asma köprü sisteminde gergi halatı, ana kablo ve askılar için P-delta etkisi tanımlanarak köprü sisteminin geometrik açıdan lineer olmayan dinamik analizi yapılırken, eğik kablo askılı köprü için kabloların doğrusal olmayan davranışları eşdeğer elastisite modülü ile göz önüne alınarak dinamik analiz yapılmıştır. Çalışmadan elde edilen sonuçlar, dalga yayılma hızının köprü sistemlerinin yer değiştirme ve iç kuvvetleri gibi yapısal tepkileri üzerinde karmaşık bir etkisinin olduğunu, dalga yayılma hızına ve dikkate alınan yapısal tepkilere bağlı olarak söz konusu tepkilerin artabileceğini veya azalabileceğini göstermiştir. Bunun yanında yakın fay yer hareketi kayıtları için dalga yayılma hızının sonsuz olması durumunda elde edilen tepki değerlerindeki uzak fay yer hareketine göre elde edilen artışın, 250 m/s dalga yayılma hızı için elde edilen artıştan belirgin olarak daha büyük çıktığı gözlenmiştir.
Anahtar Kelime: Asynchronous dynamic analyses of cable-supported bridges under near-fault ground motions
Öz: In this paper a cable-stayed bridge and a suspension bridge with closer main span lengths are considered to determine the effects of near-fault and far-fault ground motions on the structural responses of these bridges under asynchronous excitations. While the Tatara Cable-Stayed Bridge constructed in Japan is preferred as a cable-stayed bridge model, the Fatih Sultan Mehmet Bridge constructed in Turkey is considered as a suspension bridge model. While the geometric nonlinearity including P-delta effects resulting from the self weight of the suspension bridge is considered in the dynamic analysis of the suspension bridge, the nonlinearity of the cable-stayed bridge cables are taken into account with the equivalent modulus of elasticity. The results show that the traveling wave has a complicated effect on the structural responses like displacements and internal forces, and underestimates or overestimates the structural responses depending on the wave propagation velocity and the considered structural responses. It is also observed that the increment of the responses for the infinitely propagating near fault ground motions with respect to the farfault ground motions are obviously larger than the incerement obtained for the 250 m/s wave propagation velocity.
