预应力FRP加固混凝土梁性能研究

通过数值计算和试验，对外贴预应力FRP加固受弯构件的受力性能进行了研究，对加固后钢筋混凝土梁正截面的破坏特征、受力特点和影响因素以及构件变形进行分析。结果表明，计算数据与实验数据具有较好的吻合度，同时分析了造成实验数据和计算数据误差的原．因，为加固设计和计算提供必要的参考。

Behavior Research of Concrete Beams Strengthened with Prestressed FRP

This paper presents both numerical value and experimental studies of the behavior of conceret beams strengthened with prestressed FRP, discussing the load deformation p, flexural failure and various parameters influencing their behavior. The comparison of the results of numerical calculation and experimental studies has shown that they have high coherence. The paper discuss the reasons causing the errors of numerical value calculation and experimental studies for the reference of strengthened design.
