摘要 采用数值分析方法对FRP约束混凝土纯弯构件的荷载 -变形关系进行全过程分析 ,理论计算结果与实验结果吻合良好 ,在此基础上 ,本文推导了FRP约束混凝土构件抗弯承载力简化计算公式 ,公式形式简单 ,概念明确 ,便于实际应用。简化公式计算结果与实验结果吻合较好。本文的研究成果可为进一步深入研究FRP约束混凝土压弯构件的力学性能和承载力计算方法提供参考。 Based on the stress-strain model of FRP-Confined concrete,an integral method is applied to calculate the complete load-deformation curve for FRP Confined beams.The calculated results fit well with the test results.Formulas for calculating the flexural strength of the beams are developed. The formulas are convenient,and the calculated results are in good agreement with the tests.
