[提要] 介绍了三个试验,即中等高度钢筋砼抗震墙试验、一个单元的框架一抗震墙试验以及底部两层框架-抗震墙上部四层砖房模型的振动台试验。分别阐述了这类建筑在多遇、罕遇地震作用下的承载力和弹塑性变形分析。最后提出了工程应用建议,认为通过正确的抗震设计,这类建筑能用于抗震设防烈度不大于8度的地震区。
[关键词] 多层砖房 框架-抗震墙 底部剪力法 增大系数The paper briefs three tests including the test of mid-rise R.C.seismic wall, the model test of a unite structure with two-story frame-seismic wall and the shacking table test of the model for four-story masonry building supported by two-story frame-seismic wall. The paper describes the analysis of the carrying loading capacity and the elas-plastic deformation of these kind of buildings under the earthquake, Finally, the authors put foward the engineering application suggestion that the multi-story masory supported by two frame-seismic wall structure can be constructed in the seismic area if its seismic design intensity is not greater than 8 degree.
Keywords: multi-story masonry building; frame-seismic wall; bottom shear force; amplifying coefficient
