有限元仿真分析中的结构周期差异探讨

The discussion for variety of structure's natural period in simulant FEA

针对有限元仿真分析中结构自振周期减小的问题 ,讨论了几种主要的影响因素。并借用商品化设计软件TBSA ,ETABS和有限元分析软件ANSYS ,通过对一个简单结构的多次计算 。

Discussing about some influencing factors which may induce the decrease of structure's natural period in simulant FEA. Then comparing the effect of these factors by calculating a simple structure several times, using TBSA, ETABS, two design software and ANSYS, a FEA software.
