The motion differential equations were derived in storey coordinates. Combined with Fourier transform, the transfer matrix in frequency domain can be used to obtain the seismic response analysis of the frame-shear wall structure. The results show that this method is suitable for analyzing the frame-shear wall structure with variable mass or stiffness distributed along the height; and considering the mass distribution effect on the seismic response and the natural frequency of the structure is necessary.Keywords:frame-shear wall structure；interlayer distributed mass；transfer matrix in frequency domain；seismic response analysis作者簡介：祝文畏，碩士，Email:wenweiz@163.com。參考文獻［1］ 黃世敏，魏璉. 地震作用下沿高變剛度框剪結(jié)構(gòu)的計算方法［J］.建筑科學(xué),1997(4)：11-15.［2］ 文立華，尚世英，劉洪兵. 一種框架-剪力墻結(jié)構(gòu)的動力分析方法［J］.西北工業(yè)大學(xué)學(xué)報,1995，13(2):114-118.［3］ 祝文畏,張碩英.剪力墻結(jié)構(gòu)水平地震反應(yīng)的頻域分析［J］.建筑結(jié)構(gòu),2008,38(6):39-41.［4］ 包世華，方鄂華.高層建筑結(jié)構(gòu)設(shè)計［M］.北京:清華大學(xué)出版社,1990.［5］ 朱鏡清.結(jié)構(gòu)抗震分析原理［M］.北京:地震出版社,2002.［6］ 董剛,朱鏡清.結(jié)構(gòu)地震反應(yīng)分析的頻域傳遞矩陣法［J］.計算結(jié)構(gòu)力學(xué)及其應(yīng)用,1994, 11(4):435.［7］ 袁錦根. 框架-剪力墻結(jié)構(gòu)的動力分析［J］.世界地震工程,1994(1):35-41.
