摘　　要：设计6片比例为1∶2的模型墙体,通过拟静力试验研究节能砌块隐形密框墙体抗剪承载力性能,以及墙体受剪承载力的影响因素.结果表明,影响节能砌块隐形密框墙体受剪承载力的因素是多方面的,其中隐形密框的强度及墙体配筋起主导作用.通过模型墙体的拟静力试验及其数据的统计回归,定义混凝土砌块强度,配筋等对墙体抗剪影响因素的贡献值,提出节能砌块隐形密框墙体实用受剪承载力计算公式.Six 1/2-scale model walls with energy-saving block and hidden multi-ribbed frame are built to investigate the shear capacity and the influence factors by the pseudo-static test. The results indicate that there are many factors to influence the shear capacity of the wall, and the concrete intensity and reinforcement ratio are the two main factors. Based on the regression of test results, the contribution value of the concrete intensity and reinforcement ratio are defined, and a practical calculation formula of shear capacity of the wall with energy-saving block and hidden multi-ribbed frame is presented.
