摘要
由于采用动力时程分析方法对结构的设计和现有结构性能进行评价有很多不便从而使应用受到限制。本文结合基于性能的抗震设计理论和方法,运用静力弹塑性分析方法对一个三层钢结构框架进行了计算分析,并与此钢结构框架的振动台试验结果进行了对比。讨论了框架的破坏模式和抗推覆性能。
A simplified plastic zone method considering influence of plastic zone length on the stiffness matrix for elastic- plastic analysis of steel frames were introduced. Based on this theory, a conventional example was analyzed by nonlinear finite element, and the damage features as well as mechani- cal performance were discussed.
