摘要
在结构设计时,同普通剪力墙一样,短肢剪力墙也应根据受力情况的不同进行分类。本文选取75榀短肢剪力墙,利用ANSYS软件建立有限元模型,对其在水平倒三角形荷载下的内力情况进行对比分析。得出如下结论:当满足整体性系数α≥10,肢强系数ζ≤0.95时,为整体小开口墙;当满足1≤α<10和ζ≤0.95时,为联肢墙;当满足α≥10和ζ>0.95时,为壁式框架。以上可作为工程设计时对短肢剪力墙分类的判别标准。
In the process of structure design, short-pier sheer wall should be categorized according to stress situation, the same as what we do with sheer wall. This paper uses the software ANSYS to build the finite element models for 75 short-pier sheer walls, compares and analyzes their internal forces under level inverted triangular loads. It is integral wall with small openings if the integrative coefficient is greater than or equal to 10 while the pier strength coefficient ~＂ is smaller than or equal to 0. 95;it is coupled wall if the integrative coefficient a is greater than or equal to 1 but smaller than 10 while the pier strength eoeffieient is smaller than or equal to 0. 95 ; it is wall frame if the integrative coefficient ot is greater than or equal to 10 while the pier strength coefficient is greater than 0. 95. This can be used as the criteria for categorizing short-pier sheer wall in the course of engineering design.
