摘　　要：借助有限元软件MIDAS/CIVIL建立了某斜交V型墩刚构桥有限元模型,首先分析了该桥的动力特性,在此基础上进行E1地震下反应谱分析、E2地震作用下时程分析,探讨了斜交刚构桥支座剪力及位移、桥墩弹塑性地震反应,评价了该桥的抗震性能,提出了斜桥抗震设计的建议,以供参考。With the software MIDAS/CIVIL, a finite element model of a skewed V-typed rigid frame bridge was builted in this paper. A dynamic characteristics analysis was done herein. A response spectrum analysis for the bridge under E1 earthquake and a time-history analysis under E2 earthquake were done in this paper. Some seismic responses such as shear forces and displacements of bearings, elastic and plastic responses of piers have been discussed herein. The seismic performances were evalutated comprehensively in this paper, then some recommendations were pro- vided when designing the similar type of bridges, for reference.
