框剪结构在水平力作用下的一种算法

A Computation Method for Frame-shear Wall Structure Subjected to Lateral Loads

综述了框剪结构在水平力作用下计算方法的发展历史,结合工程应用,提出了一种拟弹性地基梁法,推导了该法的计算公式,并编制成软件.通过用该软件对算例进行分析比较,验证了该算法正确、简单适用,又由于可考虑结构的高振型影响,故该法精度优于连续栅片法.

This paper analysizes and summarizes the development of computing method for tall building frame-shear wall structures supjected to lateral loads, presents a pseudo - elastic foundation beam method according to engineering. A series of formulas were proposed and carried into the computer programs. This method can apply the mode - superposition method to take the influence of high vibration mode into consideration, so its computation is more accurate than continuous- grid methods.
