| 摘 要： | 依据混凝土结构基本理论，分析了预应力碳纤维片材加固混凝土简支梁的受力变形关系，推导出梁截面加载全过程的弯矩曲率关系，给出了预应力施加时的弯矩与曲率、消压弯矩与曲率、开裂弯矩与曲率的计算公式，并运用实例进行了验证。

| Abstract: | Based on the basic concept of the concrete structure, the load--defection relationship of simple supported concrete beam strengthened by prestressing CFRP sheets was analysed. Its momentcurvatures of all loading phases was deduced, the moment and curvature calculating formulas when applying prestress and eliminating press and cracking of concrete section were also given. An example revealed that all the formulas is reasonable. |
