摘　　要：建立了带框复合剪力墙板承载力计算的简化模型——带有等效斜撑的刚架,模型中考虑了复合墙板随刚度变化而产生的内力重分布现象,确定了等效斜撑的宽度和钢筋面积。基于对作为等效斜撑的夹芯板的承载力和作为刚架的边框的承载力以及复合墙板抗滑移承载力计算方法的分析,提出了带框复合剪力墙板的极限承载力计算方法。将简化模型计算结果与试验结果进行了对比分析,分析表明:应用该承载力计算的简化模型和方法分析的结果与试验结果吻合较好,说明该模型和计算方法是带框复合墙板承载力计算的一种有效的简化模型与方法。A simplifyied model for strength calculation of the composite shear wall panel with hidden frame, namely, rigid frame with equivalent diagonal strut is set up, which considers the effect of internal force redistribution of the composite wall panel due to its rigidity variation, and the width of equivalent diagonal strut and area of steel bars can be determined. The ultimate bearing capacity calculation method of the composite shear wall panel with hidden frame is developed, based on the analysis of the following beating capacity calculation methods, including sandwich panel and hidden frame idealized as an equivalent diagonal strut and a rigid frame respectively, and anti-slide of the composite shear wall panel. Calculation results of the simplifyied model are analyzed comparatively with shear experiment results of the composite wall panel. Analysis shows that the calculation results using this simplifyied model and method for strength calculation conform to the experiment results, indicating the validity of this simplifyied model and method for strength calculation of the composite wall panel with hidden frame.
