静力和动力弹塑性分析在某超限高层中的应用

Static and Dynamic Elastic-plastic Analysis in a High-rise Overrun Building

在介绍静力与动力弹塑性分析基本原理和各自优缺点的基础上,采用Midas Gen和Midas Building软件分别对某超限高层进行了计算分析,结果表明两种方法结构出现塑性铰的构件及分布大体相似,对构件性能的宏观判断也较一致,鉴于其各自的特点和实用性,实际工程设计中可根据情况进行合理的选择。

This paper introduces the basic principles of static and dynamic elastic-plastic analysis and their respective advantages and disadvantages.The static and dynamic elastic-plastic analysis has been conducted by using the software MidasGen and Midas Building.The structural component performance and the distribution of plastic hinge are similar in two analysis results,and the judgment to the macroscopic properties of structural members is more consistent.In view of the characteristics and practicality of the static pushover and dynamic non-linear analysis methods,reasonable choices can be used based on the actual engineering situation.
