摘要
本文分析比较了目前国内外计算框架剪力墙结构的常用方法,根据剪力墙变形的主要特点,采用一种墙板单元分析方法,即将墙用墙柱代替,上下端设刚域,并与框架梁柱节点铰接。本文对文献[1]的公式推导作了一些校正,导出墙板单元的刚度矩阵,编制出电算程序。用本程序分析框剪结构具有输入数据方便、计算量小、精度高以及直接给出剪力墙各分肢内力的特点。且能将剪力墙组台到框架中的任意位置上,能进行纯框架或纯剪力墙结构的分析,具有应用范围广、经济实用的优点。
Having reviewed some conventional methods of analysis of frame structures with shear walls, this paper takes advantage of a type of modelling in which shear wall panel is treated as a vertical column member with upper and lower rigid zones but hinge connected at beam-to-column joint. Making some correction for the formulation in paper [1], stiffness matrix of such element has been deduced and a computer programme compiled. Operation shows that the computer programme is distinctive by easy input, less computation, high precision and possibility of directly giving internal forces of shear walls.Moreover, it is quite easy with this method to place wall panel wherever in the frame and make analysis of frame or of shear wall alone, It is, therefore,of practical value and may find extensive use in engineering design.
