本文对多洞口剪力墙进行了二维非线性有限元分析，研究了剪力墙的剪力贡献和内力传递机理。还对几种开孔布置的剪力墙进行了参数分析。分析结果表明，每个墙体单元都形成了传递剪力的斜压压杆，其形状取决于墙板的长度，与开孔布置和加载方向无关。在此基础上，建立了多洞口剪力墙的简化抗剪模型。结果表明，该简化模型可用于钢筋混凝土多洞口剪力墙的抗剪强度评估。
In this paper, two dimensional non-linear finite element analyses for shear walls with multi-openings were conducted to investigate the shear force contributions and internal stress transferring mechanisms. Parametric analyses were also conducted for the shear walls with several opening layouts. The analytical results showed that diagonally compressive struts transferring shear forces were formed in each wall element and the shape depended on the wall panel length, regardless of opening layouts and loading directions. On the basis of these analytical results, the simplified shear resistant model of the shear walls with multi-openings was constructed. It is clarified that the shear strength of RC shear walls with multi-openings can be evaluated by the proposed simplified model.
