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。
The axial compressive strength, peak strain and stress-strain relationship of hybrid fiber-reinforced concrete confined concrete were measured by axial compressive tests of hybrid confined concrete cylinders with carbon fiber cloth, basalt fiber cloth and glass fiber cloth, Effect on concrete restraint effect. The new hybrid fiber-reinforced concrete column strength model and the whole stress-strain whole process model are established. Compared with the experimental results, the new model is found to be accurate. Compared with the Teng model, The same applies to single fiber constraints.
