• 摘要: 为了进一步简化HB-FRP(hybrid bonding FRP)加固技术的粘结滑移模型, 并基于先期研究的HB-FRP粘结滑移分区模型开展研究.在假定HB-FRP加固技术的粘结滑移统一模型表达式的基础上，推导了钢扣件部位的粘结应力分布系数.将HB-FRP加固作用分为普通FRP粘结性能和钢扣件产生的粘结性能两部分，依据能量方法，推导了FRP张拉力与滑移量的表达式.基于理论分析和数值求解，研究了界面滑移量的分布特征.基于模型试验测试结果，研究了粘结滑移统一模型中的待定系数表达式.研究结果表明：建立的HB-FRP加固混凝土结构的粘结滑移统一模型能有效预测加固界面的剥离承载力及有效粘结长度.
