Seismic response analysis of simply supported skew hollow slab bridge and the research of aseismatic construction

摘要

Simply supported slab bridges are used extensively in China. How to make them stand firmly when they encounter a great earthquake is necessary. With a conclusion of seismic hazard feature of simply supported slab bridges and Midas/civil, this paper studies the seismic behavior of a simply supported skew slab bridge in Wenchan, county Sichuan province and get the seismic response and structure's weak link of the bridge. A new method to prevent the slab from falling off is put forward.
