SDOF弹塑性体系地震响应的参数影响
|
摘要
从国外十几次主要地震事件中选取了320条强震记录,按照《铁路工程抗震规范》罕遇地震下6度、7度、8度和9度设防标准进行调幅,并利用弹塑性动力分析程序,采用Takeda双线性刚度退化模型,考虑了不同震级、场地类型、基阶周期的影响,进而对SDOF弹塑性体系的地震响应进行了参数影响研究,为建立与《铁路工程抗震设计规范》相符的弹塑性反应谱提供合理的依据,进而为桥梁结构基于性能的抗震设计提供重要的参考和依据.
320 strong motion records are appropriately selected from several earthquake events in the world.Based on Code for Seismic Design of Railway Engineering,PGA of selected seismic motions are adjusted to the standard protected earthquake intensity of 6 degree,7 degree,8 degree,9 degree under rarely met earthquake.Based on the Takeda bilinear stiffness degradation model,the elasto-plastic dynamic analysis program is used to do the parametric analysis on the seismic response of elastic-plastic single-degree-of-freedom considering seismic magnitude,site conditions and periods.So,some meaningful references are provided for establishing the elasto-plastic response spectra which can help for the performance-based seismic design for bridge.
