九层组合砌体房屋四分之一比例模型结构的抗震性能试验研究

EXPERIMENTAL STUDY ON THE SEISMIC BEHAVIOR OF A 1/4 SCALE MODEL OF NINE STORY COMPOSITE MASONRY HOUSE BUILDING

通过对四分之一比例九层组合砌体结构模型的拟静力试验，得到了这类结构的延性、耗能比、阻尼等有关的抗震性能指标，分析了结构的破坏机理。试验表明，房屋的高宽比比较大时，其整体抗弯强度起控制作用，应加强其抗弯强度的措施。

In this paper,by quasistatic test of a 1/4 scale mode of nine story composite masonry house building,the main seismic behavior index of the structure,such as ductility ,consumed energy ratio,damp etc.,are obtained,and the breaking mechanism of the structure is analyzed.The test shows that the entire bending strength of the structure takes control effect for the building with large heightwidth ratio,and the bending resistance of the structure should be reinforced.
