[提要]  根據(jù)模型試驗(yàn)數(shù)據(jù)確定各變形階段剪力墻的實(shí)際剛度，用退化降低后的剪力墻實(shí)際剛度與框架協(xié)同工作，計(jì)算出結(jié)構(gòu)地震作用和框架各樓層最大地震剪力的確切數(shù)值，給出了考慮剪力墻剛度退化框架各樓層地震剪力的簡(jiǎn)單實(shí)用計(jì)算法——修正系數(shù)法，其結(jié)果與《高規(guī)》(JGJ3-91)和《抗震規(guī)范》(GBJ11-89)的規(guī)定一致，并為上述規(guī)范提供了試驗(yàn)數(shù)據(jù)和理論分析依據(jù)。

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.
