强震作用下砌体结构变形及破坏特性试验研究

Experimental Study on Masonry Structure Deformation and Damage Characteristics Under Action of Earthquake

设计并制作了二层烧结普通砖砌体结构模型.为便于与设置有构造柱和圈梁的砌体结构及经过抗震加固后的砌体结构进行比较,本设计模型未加构造柱和圈梁.通过拟动力试验,研究了这类砌体结构的变形、开裂和破坏等性能,并对这类砌体结构进行了分析、比较.试验分析表明,这类砌体结构的滞回曲线和变形等性能与另外两种形式的砌体结构有明显的差别.

In this paper, a double-deck sintered common brick masonry structure model is designed and built. It is designed without the use of constructional columns and ring beams, in order to compare it with the brick masonry structure with the use of the two members and with the brick masonry structure under seismic strengthening. The deformation, cracking and damage features are studied by the pseudo-dynamic test. The results show that the hysteretic curves and deformation properties of this kind of brick masonry structure are obviously different from those of the other two kinds.
