[提要] 提出幾種高層建筑結(jié)構(gòu)簡(jiǎn)化分析統(tǒng)一的連續(xù)-離散化方法，即先將幾種高層建筑結(jié)構(gòu)連續(xù)化處理以后，均采用等效柱計(jì)算模型，再用矩陣位移法分析。幾種結(jié)構(gòu)等效柱的單元?jiǎng)偠染仃嚲哂型恍问剑褂?jì)算和程序設(shè)計(jì)簡(jiǎn)便，用本文的方法可以分析變剛度高層框架、框-剪和剪力墻結(jié)構(gòu)。

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
