摘要
以某典型曲线桥为例,通过大型有限元分析软件建立精细模型,采用动力时程法对不同墩高模型的曲线桥进行分析研究,讨论在相同多点激励地震动输入下不同墩高的曲线桥的地震响应,探究不同墩高对曲线桥动力特性上的影响和多点激励下的影响,分析结果可为同类型桥梁提供抗震设计依据。
A typical curved bridge is taken as an example to build a fine model with ANSYS finite element analysis software. Analysis is made on curved bridges with different pier heights by using the multi-support excitation method. And discussion is made on the seismic response of these curved bridges under the same multi-support excitation. The results may provide an evidence of seismic design for bridges of the same type.
