摘要
碳纤维增强复合材料(CFRP)具有轻质高强、耐腐蚀等优点,已被广泛应用于钢筋混凝土(RC)结构的修复加固。本研究采用OpenSees有限元软件对CFRP加固RC圆柱在水平往复荷载作用下的性能进行了非线性分析,模拟结果与试验结果较为一致,模型具有较高的精确性。在此基础上,对柱截面尺寸、轴压比、剪跨比、CFRP包裹层数、纵筋配筋率等参数对FRP加固RC柱水平峰值承载力的影响进行了详细的参数分析。
Carbon fiber reinforced polymer(CFRP)has the advantages of light weight,high strength and corrosion resistance,and has been widely used in the repair and reinforcement of reinforced concrete(RC)structures.In this paper,a nonlinear numerical analysis of the performance of CFRP-reinforced RC columns under horizontal cyclic load was carried out using OpenSees software.The simulation results were consistent with the test results,which verified the accuracy of the model.On this basis,a detailed parametric analysis of the effects of parameters such as sectional dimension,axial compression ratio,shear span ratio,CFRP layer,and longitudinal reinforcement ratio on the horizontal peak load carrying capacity of FRP-reinforced RC columns was carried out.
