摘　　要：本文在试验的基础上,提出了带边框低剪力墙的破坏形态,并对破坏机构模型化,应用塑性理论中的相关流动法则,推导了带边框低剪力墙的极限抗剪强度计算公式,较全面地考虑了影响带边框低剪力墙极限承载力的各种因素。算例表明公式计算值与试验结果相当吻合。该计算公式可应用于带边框低剪力墙的实际设计和强度复核。On the basis of the test results, the paper suggests a failure mode for framed lowrise shearwall by modelling its failure mechanism. Formulation of utilmate shear strength for framed lowrise shear-walls based on the relative flow principle of the plastic theory is made, which reasonably considers overall factors relating to shear strength of framed lowrise shearwalls. Numerical examples show that caculated results by the present analysis are in good agreement with test data. The formulas presented in the paper can be applied to practical desigh and strength checking of lowrise shearwalls.
