摘要 高层建筑钢筋砼剪力墙(或薄壁筒)和钢框架组合结构在工程中已开始使用,其高度往往超过60m,按规范应采用输入地震波进行时程分析。本文将钢筋砼剪力墙(或内筒)和钢框架分别作为分层多质点体系,组成并联双列多质点振动模型,采用步步积分直接求解动力方程方法得到地震过程中结构动力反应值。进行弹塑性分析时,钢筋砼部分采用三线性滞回线,钢结构部分采用双线性滞回线。 By tall composite building structures are generally meant steel frame-RC shear wall structures and steel frame-RC tube structures. These types of tall building structures have been used in China nowadays. Since their heights are usually over 60m, the method of time history analysis by earthquake records must be used in design according to the requirements of the new aseismic design codes.In this paper, the RC wall (or tube) and the steel frame are considered as lumped-mass system. A parallel double series lumped-mass vibration model has been used, and the responses in earthquakes are obtained by means of step by-step integration method. In elastoplastic dynamic analysis, the trilinear loop for RC wall (or tube) and the bilinear loop for steel frame are adopted.
