摘　　要：采用杆系-层间模型,提出多阶变刚度框架-筒体结构的连续-离散化方法,推导出框架-筒体结构的单元刚度矩阵和整体刚度矩阵。编制了考虑框架与筒体协同工作,并且能够分析每根杆件的结构动力时程分析程序,程序中考虑了筒体空间作用、P-Δ效应等,该程序已应用于一些高层建筑的结构分析。In this paper, by using member-story model, continuous-individual method for multi-order varied stiffiness frame-tube structures is proposed. The element stiffiness matrix and the total stiff＇mess matrix of frame-tube structure are derived. A structure dynamic analysis program which can analyse each member and reflect the interaction of tube and frame is drawnup. In this program,space action and p-A effect are considered. The program had been used in the analysis of some tall buildings design.
