摘要

通过建立超大型冷却塔三维有限元模型,在考虑土-结构相互作用情况下,对超大型冷却塔结构进行动力特性分析,并与刚性地基的结果进行对比。用反应谱分析计算了单向地震的作用和效应,并采用双向地震与自重、风荷栽、温度荷载工况进行了组合,得到了相应工况的内力和位移,为工程设计提供了参考。
A three-dimensional finite element model was built for super large cooling tower.Comparing with the results of rigid foundation,the analysis of dynamic characteristics was carried considering soilstructure interaction.Effect and response under unidirectional earthquake action were calculated by response spectrum analysis.Furthermore considering bilateral seismic conbined with dead weight,wind load,and temperature load condition,the internal force and displacement of corresponding condition were also obtained, they would provide reference for engineering designing.
