框架结构层间位移的分析方法比较

The research for solving the interstorey displacement of frame structures under horizontal load

针对框架结构的受力特点,从有限元法和近似计算法两个方面分析了框架结构在水平荷载作用下层间位移的求解方法,并将其计算结果进行对比,分析了近似算法误差的原因,同时也证明了近似计算法是一种能够满足误差要求的简化计算方法。

Basing on the loading characteristic of frame structures, the approach to solving interstorey displacement under horizontal load has been analyzed from finite element method and approximate calculation method. Moreover, the comparing analyse of two calculation result has been carried out in this paper. The error causation is put forward, the calculation result shows the approximate calculation method is a simplified method of satisfy the error requirement.
