［提要］  首先利用底部剪力法分析了多層剪切型框架結(jié)構(gòu)的地震作用與質(zhì)量和剛度變化的關(guān)系，進(jìn)而研究了由于填充墻數(shù)量和位置的變化而引起結(jié)構(gòu)質(zhì)量和剛度的變化情況，指出對應(yīng)質(zhì)量和剛度上限的完全填充狀態(tài)是地震作用的最不利狀態(tài)，提出了計算填充墻框架最不利地震作用的包絡(luò)設(shè)計方法。

Seismic Envelope Design Methods of Frame Structures Considering Changes of Infilled Walls/ Cheng Zhihui,  Zhang Xiaowen(Architectural Design & Research Inst. South China University of Technology, Guangzhou 510641, China)

Abstract:The relationship between earthquake action and the changes of mass and rigidity is analyzed with the equivalent base shear method. The variation in number and location of infilled walls resulting in changes of mass and rigidity of structures is studied. The fullfilled state corresponding to the upper limits of mass and rigidity is the most disadvantaged. The seismic envelope design methods of frame structures with infilled walls are given.

Keywords:frame structures with infilled walls； equivalent base shear method； mass； rigidity； earthquake action
