摘要
归纳已有的FRP约束混凝土强度计算模型,并结合实例对其进行可靠度分析,同时考虑在混凝土抗压强度变异系数和FRP抗拉强度变异系数不同时,各计算模型的可靠指标的变化趋势,得到了一些有意义的结论。最后提出了FRP约束混凝土的设计计算建议。
It concluded the existing strength models for fiber-reinforced plastic-confined concrete.Combined with the example,the reliability analysis on the models is utilized.The tendency of reliability indexes of calculating models, with the changing of the variation coefficient of concrete compression and the variation coefficient of tensile strength of FRP.Some valuable conclusions and suggestion on design calculation of fiber-reinforced plastic-confined concrete are obtained.
