[提要]  基于剪力墻高度不同對(duì)框-剪結(jié)構(gòu)地震反應(yīng)的影響，以及不是對(duì)所有的框-剪結(jié)構(gòu)都需要把其剪力墻延伸至整個(gè)結(jié)構(gòu)高度的結(jié)論，作者采用桿系-層間模型對(duì)剪力墻高度不同的、剪力墻剛度中斷的框-剪結(jié)構(gòu)模型進(jìn)行地震響應(yīng)分析，得出了剪力墻可在框-剪結(jié)構(gòu)反彎點(diǎn)以上截?cái)嗟挠^點(diǎn)。同時(shí)，確定了該模型結(jié)構(gòu)的轉(zhuǎn)換層處樓層剛度比，并以此作為衡量轉(zhuǎn)換層是否需要加強(qiáng)的具體技術(shù)指標(biāo)。

In references to the seismic responses of frame-shear wall structures with shear wall interruption, it was concluded that not all frame-shear wall structures need to extend their shear walls to the height of entire structure. The seismic responses of frame-shear wall with different shear wall interruptions are studied by using the member-story model, a conclusion is given that the shear wall should be interrupted above the point of inflection of the structure if need. At the same time, the transform floor stiffness ratio of the model structure is confirmed and taken as the criterion to determine that the transform floor is reinforced or not.
Keywords: frame-shear wall structure; stiffness interruption; transform floor; point of inflection; story stiffness ratio
