摘　　要：多层混合结构房屋在我国居住房屋中占有相当的比例,临街多层住宅底层"破墙开店"等野改蛮装造成结构安全隐患的现象严重,一旦倒塌将会造成全楼及周边生命财产损失。对于底层"破墙开店"的多层混合结构住宅的加固补救在我国是必须关注的一个重要问题。分析探讨了几种可行的补救加固方法。分析表明,弥补刚度缺失,恢复原结构刚度中心位置十分关键。Multi - story masonry structure buildings take up a considerable proportion of the existing dwelling houses in China. The underlying ＂tearing down the wall or widening window for shopping usage＂ caused lots of hazard problems, when the building structures collapse, may lead to serious losses of the lives and properties. So the reinforcement and remedial measures of the danger structures are of great significance. By structural analysis, several feasible reinforcement methods to recover the safety of building are suggested. Among all the methods suggested, that to reset the removed stiffness and to recover the stiffness centre position is of the most important.
