摘要
以有限元软件ANSYS为分析工具对二次受力状态下碳纤维布加固钢筋混凝土梁的受弯承载力进行了非线性分析,并与试验值进行对比,结果表明:ANSYS计算值与试验值吻合较好,初始荷载的存在会降低碳纤维布加固的效果,建议在实际加固工程中尽可能卸载,以保证加固效果。
A nonlinear finite element method is used to analyze the flexural capacity of RC beams strengthened with CFRP by using ANSYS software. It is compared with experimental values. As a result, they are good agreement. The existence of the initial loading will reduce the strengthening effect. Proposed reinforcement as much as possible the actual unloading to ensure the strengthening effect.
