[提要]  根据模型试验数据确定各变形阶段剪力墙的实际刚度，用退化降低后的剪力墙实际刚度与框架协同工作，计算出结构地震作用和框架各楼层最大地震剪力的确切数值，给出了考虑剪力墙刚度退化框架各楼层地震剪力的简单实用计算法——修正系数法，其结果与《高规》(JGJ3-91)和《抗震规范》(GBJ11-89)的规定一致，并为上述规范提供了试验数据和理论分析依据。

Determining real stiffness of wall in different deformation phases according to the experimental data, walls with degraded stiffness work in coorpration with the frames, earthquake action of the structure and story maximum seismic shear force of frame are calculated accurately. A practical and simple method-correction coefficient method which can determine the story seismic internal force of frames with consideration of stiffness degradation of walls is presented. The result from the method is perfectly compatable with the specification (GBJll-89)and (JGJ3-91) and provides the supporting facts in experimental data and theory analysis for above specifications.
