摘要
为确定纤维增强塑料(FRP)约束混凝土圆柱体轴心抗压强度的计算方法,以相关研究成果为基础,对具有代表性的FRP约束混凝土强度模型进行了对比分析,并将这些强度模型的计算值与已有的相关试验数据进行了比较,在此基础上,建立了改进的FRP约束混凝土圆柱体轴心抗压强度计算的简化模型。改进的FRP约束混凝土强度模型计算值与大量试验数据吻合良好,能够反映FRP约束混凝土的真实特性,研究成果可作为工程实践的参考依据。
In order to confirm the calculating method of FRP confined concrete circular columns in engineering practice and based on relevant results of studies, authors analyzed the representational FRP confined concrete strength models and compared the value of these models with the data of relevant experiments, and then proposed an improved simplified model for calculating axial compressive strength of FRP confined columns. The value of this model could tally with the experimental results and could show the actual property of FRP confined concrete. The proposed model may be a reference for practical engineering.
