| 摘 要： | 为探讨大跨度悬索桥梁抗震设计理论问题，利用基于大质量法的多支承激励运动方程，研究非线性多支承激励地震响应，分析桩-土-结构相互作用对动力特性和地震反应的影响，以及行波效应对地震反应的影响。分析表明，主塔为嵌岩桩时，考虑桩基础的桩-土-结构相互作用后会使结构的内力反应减小，行波效应对结构内力反应影响不大，加劲梁与边梁在主...

| Abstract: | In order to investigate theoretical issues in wind and earthquake resistance design of large-span suspension bridges,this paper studies the response of nonlinear multi-support excitation to earthquake by means of motion equations of multi-support excitation based on the large-mass method(LMM),and analyzes impacts of interactions of pile-soil-structure on dynamic properties and seismic response and influences of traveling wave effect on seismic response.In accordance with the analysis of the paper,the travel... |
