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。
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 stiffiness 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 drawn up. In this program, space action and P Δ effect are considered.The program had been used in the design of some tall buildings.
