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
