摘 要: 分别选取无洞和开洞墙体,利用ANSYS有限元软件,模拟在低周反复荷载作用下有无洞口的墙体破坏机理,再比较2片墙体分别添加构造柱的情况,从强度、刚度、延性、极限位移及抗震性能等多项性能指标进行分析,从理论上验证该加固方法的可靠性,具有重要的现实意义。
关 键 词: 结构工程;构造柱;砌体结构;有限元法;抗震性能

Abstract: This paper respectively introduced two models with/without a window cut based on FEM with ANSYS software, then input low cycle and alternating loads on the lateral points of the top beam, doing numerical simulation on failure mechanism of these two walls. Finally, compared the cases after adding tie columns to these walls, analyzed on strength, stiffness, ductility, limiting displacement and seismic resistance and etc. The results of this research are significant, it verified the reliability analysis of this method of strengthening in theory.
Key words: structural engineering; tie column; masonry structure; finite element methods; seismic resistance
