Özet

In this paper a cable-stayed bridge and a suspension bridge with closer main span lengths are considered and the bridge responses obtained from the near-fault and far-fault ground motion cases are compared for both bridge models to underline the relative importance of earthquake ground motions on the bridge responses. As expected, near-fault ground motions have resulted much larger response values for both bridge models if compared with far fault ground motions. The results of the study also underline that, pulse type near-fault ground motion effect on the suspension bridge model is severe than those of the cable-stayed bridge model. (C) 2017 The Authors.
