摘要
根据预应力碳纤维布加固钢筋混凝土梁的不同受力阶段,给出了各阶段预应力碳纤维布应变和应力的计算方法;根据混凝土结构设计规范,提出了预应力碳纤维布加固有初始荷载的钢筋混凝土梁正截面抗弯承载力计算公式,并给出了公式的适用条件和计算方法。
An analytical method for the strain and stress of prestressed carbon fiber reinforced polymer （CFRP） sheet is proposed according to different stress stages of reinforced concrete（RC） beams strengthened with prestressed CFRP sheets. And the basic calculation formulas of the flexural capaci- ty of the initial loaded RC beams strengthened with prestressed CFRP sheets are presented based on the design code of the RC structure. Finally, the application conditions and calculation methods of the formulas are also put forward.
