[提要] 提出几种高层建筑结构简化分析统一的连续-离散化方法，即先将几种高层建筑结构连续化处理以后，均采用等效柱计算模型，再用矩阵位移法分析。几种结构等效柱的单元刚度矩阵具有同一形式，使计算和程序设计简便，用本文的方法可以分析变刚度高层框架、框-剪和剪力墙结构。

This paper presents a unified continuum - discretization method for calculating several types of tall building structure. After connecting beams are treated with continuum technique, equivalent column is all used as the calculation model and then the structure is analyzed by the matrix displacement method. The element stiffness matrixes of equivalent column of several types stucture have the same form, so calculating and programing are simple. Tall frame, wall- frame and shear wall stuctures with variable stiffness can be analyzed by the suggested method.
Keywords: tall building; variable stiffness; calculation model; matrix displacement method
