约束灌芯混凝土砌块砌体轴压性能试验研究

Experimental study on the behavior of confined grouted concrete block masonry under axial compression

以配筋砌块剪力墙结构端部受压区为研究对象,通过试验方法研究配筋砌块剪力墙端部受压区采用箍筋等约束后对剪力墙抗震性能的影响.共进行了24个采用8种不同方案的约束灌芯混凝土砌块砌体轴压试验,了解了约束灌芯混凝土砌块砌体轴压的破坏形态、承载能力和变形特征.通过对试验数据的分析,较详细地研究了各种形式横向约束件对灌芯混凝土砌块砌体强度和变形的影响,由试验分析结果可知:采用合理约束形式的约束砌块砌体的受压性能得到较大程度的改善.

The border compression zone of reinforced concrete block shearwall was studied. Experimental research on its seismic behavior affected by the confined stirrups was done. In total, 24 tests were conducted for 8 kinds of pattern Under axial compression. Failure mode, bearing capacity and deformation characteristic of confined grouted concrete block masonry strength and deformation was discussed were achieved. The influence of the different confined patterns on its From the analysis results, it can be seen that the compressive capacity of confined block masonry can be improved by the appropriate pattern.
