摘要

摘要: 通过对碳纤维布、玄武岩纤维布和玻璃纤维布混杂约束混凝土圆柱的轴心受压试验，测得了混杂纤维布约束混凝土的轴心抗压强度、峰值应变、应力-应变关系，分析纤维布混杂方式对混凝土约束效果的影响。建立新的混杂纤维约束混凝土柱强度模型和应力-应变全过程整体模型，通过与试验结果比较，发现新的模型计算准确，与Teng等的模型相比，不需要分段拟合，计算简单，且同样适用于单一纤维约束情况。

Abstract: The bearing capacity, peak strain, stress-strain relation of circular concrete columns confined by CFRP, BFRP, GFRP and hybrid FRP were analyzed under axial compressive load.The confinement effects of hybrid FRP on concrete columns were analyzed.A strength simulation model and a stress-strain whole process simulation model of hybrid FRP confined concrete columns were presented.The new stress-strain whole process simulation model has good simulation accuracy and does not need piecewise fitting compared with single FRP model provided by Teng et al.The new simulation model is also suitable for single FRP confinement cases.
