基于MSC.MARC的结构拆柱加固分析

Analysis of dismantling-column reinforcement based on MSC. MARC

既有建筑的改造中,为了满足建筑布局的要求,部分结构构件需要拆除。本文结合实际工程,讨论建筑的改造中,结构拆柱的加固方法,并运用有限元分析软件,对结构加固后的相关构件进行受力分析。分析结果表明,本文的钢-混凝土组合梁加固方法能既满足结构加固要求,又满足建筑布局要求。

In order to meet the requirement of building layout,part of the structure needs to be removed in old building reconstruction. Combined with actual project in this paper,the reinforcement method of dismantling-column is proposed in old building reconstruction,and the forces of the structural strengthening are analyzed by using the finite element analysis software. The analysis shows that the reinforcement method of steel-concrete composite beam can not only meet the requirement of structure reinforcement,and satisfies the requirement of building layout.
