摘要

摘要: 考虑复材纤维（FRP）筋与混凝土之间的拉伸刚化现象，建立了FRP筋混凝土梁的条带法分析程序，对FRP筋混凝土梁的弯曲过程进行数值模拟分析。基于数值结果提出了弯矩-曲率三线性简化模型，该模型可以较好地模拟FRP筋混凝土梁的抗弯性能。在试验验证的基础上，探讨了配筋率及混凝土强度等因素对FRP筋混凝土梁弯曲性能的影响。

Abstract: With the consideration of tension stiffness between FRP bars and concrete, a finite strip analysis procedure for FRP bar concrete beams was established and the bending behavior of FRP bar concrete beam was simulated. Based on the numerical results, a simplified trilinear model for moment-curvature of FRP bar concrete beam was proposed and verified. After verification of the calculated results with experimental results, a parametric analysis was conducted.
