| 摘 要： | 在地震工程研究中同时考虑局部地形效应和土与结构动力相互作用对结构动力响应的影响是一个困难的问题。该文基于多源粘弹性人工边界理论，利用通用有限元程序ANSYS建立了一种可以同时考虑地震波入射角度、土与结构动力相互作用及局部地形效应等因素影响的有限元分析模型。利用这一模型对一座5跨连续梁桥进行了动力响应分析，结果表明：结构...

| Abstract: | The seismic response analysis of the structure considering both topographic effect and soil-structure dynamic interaction simultaneously is a difficult problem in earthquake engineering research.Based on the viscous-spring superposition artificial boundary theory,a finite element model accounting for the incident angle,soil-structure dynamic interaction and topographic effect is built by using the ANSYS and a seismic response analysis of a five-span continuous beam bridge was carried out by the method.The n... |
