摘要
为研究玄武岩纤维加固钢筋混凝土圆柱的疲劳性能,利用ABAQUS对不同应力比和不同加固层数的钢筋混凝土圆柱进行了有限元分析.分析结果表明,玄武岩纤维布的加固能有效提高钢筋混凝土柱的疲劳性能,且包裹层数对钢筋混凝土圆柱的疲劳性能有较大影响.通过分析有限元计算结果,提出了疲劳荷载下玄武岩纤维加固钢筋混凝土柱的最优粘贴层数.
In order to get fatigue properties of reinforced concrete columns strengthened with basalt fiber reinforced polymer（BFRP）, the finite element analysis for different force ratio and reinforcement layers were analyzed by ABAQUS. The analysis results showed that BFRP reinforcement could effectively improve the fatigue performance of reinforced concrete columns and the fatigue performance of reinforced concrete columns wrapped layers had a con- siderable influence on it. The optimal layers of reinforced concrete columns strengthened with basalt fiber under fa- tigue loading were identified by analyzing the results of finite element calculation.
