| 摘 要： | 在收集、整理国内外FRP约束混凝土圆柱体反复受压试验数据的基础上,考察了FRP约束混凝土卸载及再加载应力—应变曲线的滞回特征,建立了卸载及再加载曲线的数学描述;结合J.G.Teng的单调应力—应变本构模型,建立了适用于圆柱的FRP约束混凝土滞回本构模型;对于圆柱体试件,所提滞回模型与试验结果吻合很好。

| Abstract: | Based on collecting experimental studies of FRP confined concrete under cyclic axial load during recent decades,the character of FRP confined concrete loading and unloading stress-strain curves was analyzed and the mathematic expression of cyclic rules for loading and unloading are developed.The hysteretic constitutive model of FRP confined concrete was established finally by combining with J.G.Teng＇s uniaxial monotonic stress-strain model.For cylinder concrete specimen,the theoretical solution of hysteretic constitutive model has a good agreement with relevant experimental results. |
