轻钢结构在地震作用下的变形分析

On the deformation analysis of the light steel structure under the earthquake effect

介绍了多层轻钢框架结构在抗震方面的发展,以一个轻钢框架的设计为例子,用通用软件ANSYS对结构的动力特性及抗震性能进行了分析,并与专用软件PKPM的计算结果进行比较分析,最后得出轻钢结构在地震作用下主要的控制因素是层间位移。

The paper introduces the development of the multi-layer light steel frame structure in the aspect of the earthquake, analyzes the mechanical property and the anti-seismic performance by the software ANSYS by taking the design of the light steel frame as an example, com- pares the calculation results with the one by the professional software PKPM, and concludes the light steel structure＇s major control factor is the story drift under the influence of earthquakes.
