【摘要】 运用纤维模型法对CFRP(碳纤维增强塑料)约束圆形混凝土柱的荷载-挠度全过程曲线进行了模拟,计算的全过程曲线及极限承载力与试验结果基本吻合,表明纤维模型法的可行性和合理性。然后在参数分析的基础上考察了混凝土强度、含FRP率、截面配筋率、长细比等参数对构件力学性能的影响。更多还原

【Abstract】 Fiber model was used to predict the load-deformation relationship of circular concrete column confined by carbon fiber reinforced plastics (CFRP). The predicted curves and load-carrying capacities agreed well with those of test results, which demonstrated the accuracy of the analytical model. Parameter analysis was performed to analyze the effects of longitudinal reinforcement ratio, slendemess ratio, load eccentricity and FRP ratio on load-carrying capacities of the columns.更多还原
