摘　　要：为探究CFRP(碳纤维复合增强材料)加固钢筋混凝土梁对其受弯力学性能的影响,采用ABAQUS有限元分析软件建立模型,设计7条不同类型的加固钢筋混凝土梁,以CFRP材料侧贴高度及侧贴层数为变量进行数值分析.模型试验结果表明,加固后钢筋混凝土梁内应力重分布,结构梁损伤程度减轻,增加结构整体耗能,侧贴CFRP抑制结构梁挠度变形.同时得到侧贴CFRP结构梁的最佳侧贴高度及侧贴层数,为今后钢筋混凝土梁抗震加固提供一定理论依据.In order to explore the influence of CFRP(carbon fiber composite reinforced material)reinforced reinforced concrete beams on their bending mechanical properties,the ABAQUS finite element analysis software was used to establish a model,and 7 different types of reinforced reinforced concrete beams were designed.The number of sticking layers is a variable for numerical analysis.The model test results show that the internal stress of the reinforced concrete beam is redistributed after reinforcement,the damage degree of the structural beam is reduced,and the overall energy consumption of the structure is increased.The number of side⁃attached layers provides a certain theoretical basis for the seismic strengthening of reinforced concrete beams in the future.
