Article Preview

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 seismic analysis were constituted and nonlinear time history adopted, so mechanism of abutment failure modes(strength failure, whole slide and admixture failure )was obtained. Control variables between beam and abutment were discussed. Those variables were keys of research influence on fall-off by abutment failure.
