摘　　要：以西藏某工程为例,基于大型有限元分析软件Midas GTS NX,应用不同的抗震分析方法研究进水塔在地震作用下的结构动力响应,并对比分析了各方法计算结果之间的差异。结果表明,采用不同的抗震分析方法计算得到的进水塔应力水平相差较大,但应力分布规律相同,并且采用振型分解反应谱法计算得到的结构抗震分析应力结果更加保守;在考虑地震作用的效应折减系数后,采用不同抗震分析方法导致的结构应力水平差异对结构的配筋结果影响较小。In this paper,taking a project in Xizang as an example,based on the large-scale finite element analysis software Midas GTS NX,different seismic analysis method are used to study the structural dynamic response of the intake tower under earthquake action,and the differences between the calculation result of each method are compared and analyzed.The result show that the stress levels of the intake tower calculated using different seismic analysis method differ significantly,but the stress distribution pattern is the same.Moreover,the seismic analysis result of the structure calculated using the mode decomposition response spectrum method are more conservative;After considering the reduction factor of seismic effects,the difference in structural stress levels caused by different seismic analysis method has a relatively small impact on the reinforcement result of the structure.
