【摘要】 文章以贵州省六盘山市一座不对称连续刚构桥为工程实例,利用结构分析软件MIDAS CIVIL建立了该桥的有限元分析模型,并选用Taft波与时程分析法计算了该桥的地震响应情况。结果表明桥墩是地震作用下全桥受力最不利的位置,必须重视桥墩的抗震设计和验算。更多还原

【Abstract】 With an asymmetric continuous rigid frame bridge in Liupanshan City of Guizhou as the engineering case, the article used the structural analysis software MIDAS CIVIL to establish the finite element analysis model of this bridge, and calculated the seismic response situation of this bridge through selecting the Taft wave and time history analysis method.The results showed that the pier is the most unfavorable position of entire bridge force under the impact of earthquake, thus it is required to attach the importance to the seismic design and checking computing of bridge piers.更多还原
