摘要
应用有限元程序ANSYS对结构整体进行了计算,并用振型分解反应谱法分析了其在地震作用下的响应,通过分析,得出该结构自振特性及其在水平和垂直地震作用下的不同特征。
By using the finite element ANSYS, the paper calculates the whole structure, and analyzes its response under the earthquake action by using the mode-superposition response spectrum method, obtains the natural vibration characteristics of the structure and its different characteristics under the vertical and horizontal earthquake action through the analysis.
