摘要
本文吸取离散化方法和连续化方法的各自优点，借鉴有限条方法的理论，提出了一种分析高层建筑框筒结构的简化方法，在引入广义条元的概念后，对广义条元内的梁、柱进行不同的处理，通过位移变换，分别得到了梁、柱线的广义刚度矩阵，进而又形成广义条元的广义刚度矩阵．文中还推导出几种常见荷载的广义荷载向量计算公式。
Based on the finite strip method and combining the continuum method with the discrete method,a simplified method is put forward to analyze High rise Frame tube Building Structures in this paper.After the concept of the generalized strip element is introduced, the beams and columns in the structures are treated respectively.The generalized stiffness matrices for the beam and column line are derived through displacement transform. Furthermore, the generalized stiffness matrix of a generalized strip element is assembled.In addition, the formulas for the generalized loading arrays are found out and a numerical example is given.
