Abstract:Well seismic performance of abutment were safety precondition of whole bridge. According to destroyed multi-span simple beam bridge of Wenchuan earthquake, failure modes of abutment were summarized. On the basis of correlation literature home and overseas, analysis methods of abutment seismic research were investigated. Nether factors should be take into account : soil-abutment interaction, abutment stiffness, bridge span number, pier’s force-displacement curve , bearing stiffness and etc.. Interspace model of… Show more
