摘要
文章利用大型有限元分析软件ANSYS对烟气脱硫用吸收塔进行了抗震性能分析,包括有限元模型的建立、结构动力特性分析和利用时程分析方法计算地震作用下结构的变形和内力;结果表明,结构符合国家现行规范要求,计算方法和相关结论对于运用有限元软件计算超高层建筑有借鉴价值。
The FE analysis software ANSYS is used to analyze the seismic performance. The FE model is established, the structural dynamic characteristics are analyzed and the distortion and internal force of the structure under an earthquake are calculate based on time-history analysis. The structure is in accordance with current specifications. The computational methods and relevant conclusions presented in this paper have some reference values for the calculation of super high-rise buildings by using ANSYS.
