【摘要】 本文采用通用有限元软件ANSYS,分析了地基与冷却塔的相互作用效应(SSI效应)对大型冷却塔动力特性的影响。在此基础上,进一步分析了地基阻尼比对冷却塔结构地震作用效应的影响。然后,对超大型冷却塔的结构设计提出了一些关注点。有关成果可为类似工程提供一些参考。更多还原

【Abstract】 By finite element analysis software ANSYS,the influences made by interaction between foundation and cooling tower to the hyperbolic cooling tower′s dynamic characteristic have been analyzed in this paper.Based on the results of the above research,the influence of the damping ratio to the structural seismic effect has been analyzed.Then,some concerns of the design of the large scale cooling tower have been put forward.The conclusions could be the used to the similar project.更多还原
