单元式幕墙组合立杆计算模型对比分析

组合构件通常有三种计算模型:①假定相邻构件间存在着有效抗剪连接的整体计算;②假定相邻构件能够协同变形的同步计算;③假定构件间无相互影响的独立计算。经过对单元式幕墙组合立杆的构件断面受力变形分析后,可以知道实际工程除非与假定条件吻合,否则均会存在或多或少的偏差。本文对变形受限和部分抗剪连接的情况进行分析,以探讨选择偏差最小的计算模型的方法。

Composite members usually have three models:first,assuming that effective shear connections exist between adjacent components calculated in total;second,assuming that adjacent components to deformations calculated simultaneously together,third,assuming no interaction between the components separately.However,through the combination of unit curtain wall components section of the pole after analysis of force and deformation,you know the practical unless the consistent with the assumptions,or will exist more or less deviation.This article to restricted deformation and analysis of partial shear connection to explore select the method of calculation of the minimum deviation model.
