摘要：为了分析短肢剪力墙的双向偏压正截面承载力，本文编写了基于插值原理的双向偏心受压正截面承载力分析程序.程序计算混凝土的内力完全按数学公式给出积分区域的精确解，避免了划分网格方法造成的误差.程序的计算结果与试验结果符合良好，为类似程序开发提供一条新的解决思路.利用程序得出的短肢剪力墙双向偏压N-M相关曲面，并发现曲面上的等轴力线和异形柱类似.利用本程序可以全面把握短肢剪力墙的双向偏心受压正截面承载力，能满足工程设计的要求.

Abstract: In order to analyze the cross-section bearing capacity of bi-eccentric compressive short-limed shear wall,the authors designed the analyzing program of bi-eccentric cross-section bearing capacity.Based on the interpolation principle.The program calculates the inward pressure of concrete fully according to the accurate solution of integral region obtained by mathematical equation,so as to avoid the errors of mesh generation.The program results agree well with the exprimental results.This method provides a new idea to develop similar program.By using that program,the interrelated curved surface N-M of bi-eccentric compression of short-limbed shear wall is obtained,and it is found that the equiaxed force line is similar to special-shaped column.The program can fully grasp the cross-section bearing capacity of bi-eccentric compressive short-limbed shear wall,and thus it can meet the requirements of engineering design.

Key words: short-limbed shear wall, computer program, the cross-section bearing capacity
