地震作用下多层砌块房屋墙体倾覆力矩的计算方法

A method for calculating overturning moment of multi-storey block structures under earthquake

多层混凝土砌块房屋抗震设计时,仅考虑地震引起的剪力作用和整体房屋的抗倾覆性能是不全面的。为此,提出了多层砌块房屋墙体倾覆力矩的计算与分配方法,通过典型砌块房屋的算例,利用本方法得到的墙体倾覆力矩与有限元结构分析软件SATWE的结果相近,证明了该方法的实用性,为多层砌块房屋抗震分析提供了有效手段。

It isn′t complete that the general design of block building only focuses on interstory shear and base overturning effect. A simple method for calculating overturning moment is presented and its calculated results agree well with those of the SATWE(Space Analysis of Tall-building with Wall-Element) for a typical example of block structure. It indicates that this method is a practical approach and provides effective means for seismic analysis of multi-storey block structures.
