预制圆孔板剪力墙轴心抗压试验与分析

通过两个预制圆孔板剪力墙试件的轴心抗压试验，结果表明：其破坏形态为压坏，受压承载力很大，平面外位移小，不会发生失稳破坏。采用混凝土结构设计规范的公式计算试件的正截面受压承载力，计算结果与试验结果符合较好。最后进行了非线性有限元分析，进一步为预制圆孔板剪力墙装配整体式住宅建筑体系的推广应用提供理论依据。

AXIAL COMPRESSIVE TEST AND ANALYSIS OF PREFABRICATED HOLLOW SHEAR WALLS

The experiments for two specimens under axial compression were carried out to investigate the mechanical behavior of the single prefabricated hollow shear wall. Experimental results indicate that： the failure mode of the specimens is compressive failure; the specimens have quite high axial compressive bearing capacity and small out-of plane displacement, and instability will not occur. Moreover, the axial compressive bearing capacity was calculated by the formula of ＂Code for design of concrete structures＂, and the calculating results agree well with the test results. At last, nonlinear finite element analysis was carried out, which provided a theoretical base for practical application of the new prefabricated hollow shear wall house structure system.
