【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,对结构进行动力特性分析,与刚性地基的结果进行了对比。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、风荷载、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。更多还原

【Abstract】 A three-dimensional finite element model is built for super large cooling tower.Considering soil-structure interaction cases,a dynamic characteristics analysis is carried out on the structurecondition of soil-structure interaction,and compared with the results of rigid foundation.Effect and response of unidirectional earthquake are calculated by response spectrum analysis.Bilateral seismic is combined with weight,wind load,and temperature load condition.The internal force and displacement of corresponding condition can be obtained.It provides reference for engineering design.更多还原
