摘　　要：结合混凝土结构加固过程中先卸载再进行加固的实际情况,考虑碳纤维片材加固钢筋混凝土受弯构件的二次受力特性,给出了外贴碳纤维加强复合材料加固钢筋混凝土受弯构件的承载力理论计算公式。Combined with the practical condition of reinforcement-after-uninstall in the process of concrete structural reinforcement and considered with secondary force characteristics of reinforced concrete bending member reinforced with carbon fiber sheet materials, the article proposes the computational formula of bearing capacity of reinforced concrete bending member reinforced by external plastering carbon fiber composite materials.

关 键 词：加固 二次受力 应变滞后 碳纤维片材
