矮塔斜拉桥弹塑性地震响应分析

Analysis of the elastoplastic seismic response of the low tower cablestayed bridges

通过对实际工程的建模分析,针对结构在罕遇地震作用下进入弹塑性阶段的特性,采用有刚度退化的武田三线型滞回模型,运用弹塑性动态时程反应分析法对结构在罕遇地震下的特性进行研究。

As the structure will come into the state of plastic under rare earthquakes,through the modeling analysis of the actual projects,this paper applies the Takeda degrading trilinear mode with stiffness degradation and uses the method of elastic plastic dynamic time reaction analysis to study the characteristics of structure under the rare earthquakes.
