水平荷载作用下求解刚架内力的一种渐近解法

An Asymptotic Method of Analyzing Frames withHorizontal Load

水平荷载作用下的有侧移刚架的一种渐近解法,即剪力分配法与力矩分配法联合求解刚架内力（弯矩）,将刚架的内力可展成等比级数,求得级数的首项与公比,直接进行弯矩计算。该渐进解法与其他渐近解法相比较,具有计算简单、精确、适用性强等优点。

This paper studies an asymptotic method of the frames with lateral displacement which is loaded at nodes in the horizontal direction. The method involves combining shearing force distribution with moment distribution, which analyses the internal force of the frames, and it can be expressed in series of equal ratio, the ratio and the first term of the series are also obtained. The method has such advantages as simpler, more accurate and wider applicable calculation over other methods.
