［摘要］常用设计软件沿用框架-剪力墙结构的计算方法计算部分框支剪力墙结构框支框架承担的倾覆力矩比例。但直接采用抗规方法的计算结果并不符合规范原意，且结果通常明显偏小，对规范提出的框支框架承担的倾覆力矩比例限值起不到控制作用。力学方法的计算假定与抗规方法不同，其计算结果一般偏大，导致结构往往难以满足抗规的限值要求。从框支剪力墙结构在水平荷载作用下的力学简图出发，讨论了两种计算方法的差别，并提出了推荐方法及其在设计软件中的实现方式。通过4个典型算例的计算对比表明，推荐方法更能反映框支框架在结构底部的刚度贡献，符合抗规避免部分框支剪力墙结构底部形成少墙框架的意图。

Abstract:When calculating overturning moment carried by frame part of part frame supported shear wall structure, the calculation method of frame-shear wall structure is usually adopted by current traditional design software. But the results calculated by seismic code method directly do not meet the code intent and are usually too small, which would not achieve control action of overturning moment ratio carried by frame part. The calculation assumes of mechanics method and seismic code method are different and its calculation results are usually too large, which are difficult to meet the requirement of code limitation. Starting from mechanical calculating diagram of part frame supported shear wall structure under horizontal load, the differences of the two methods were discussed. The recommended  method and implementations in design software were proposed. The calculated result analyses of four typical part frame show that the recommended method can better reflect the stiffness contribution of frame part to the bottom of the structure, which conforms the code intention that avoiding bottom part frame supported shear wall structure at least wall frames.

Keywords:overturning moment carried by frame part; part frame supported shear wall structure; mechaniscs method; seismic code method
