摘要
本文以砌体砖墙的斜拉筋加固、钢筋网加固以及粘贴碳纤维布加固为研究对象,根据加固方式的不同运用ANSYS有限元软件建立了5片墙体模型,进行了模拟低周反复加载,得到了各模型的滞回曲线、墙体应力云图、加固钢筋和碳纤维布应力分布及砖墙破坏情况等。分析计算结果表明,三种加固方式均可有效提高墙体抗剪承载力,延缓墙体开裂,其中斜拉钢筋强度利用率最高且钢筋用量更经济,效果较好。
This paper analyzed the cable-stayed steel reinforcement, steel mesh reinforcement and carbon fiber reinforcement for masonry wall by finite element method,set up and analyzed five finite element models under the low cyclic loading test by ANSYS software.Through the hysteresis curve,distortion of stress and the crack distribution of the finite element models,we observed that these reinforcement methods can effectively increase the shear bearing capacity and ductility of the masonry wall,and the cable-stayed steel reinforcement is the most efficient and economic method.
