纤维布抗弯加固梁跨中剥离应力的近似计算

AN APPROXIMATE CALCULATION FOR MIDSPAN PEELING STRESS OF CONCRETE BEAM STRENGTHENED WITH FIBER REINFORCED POLYMER

摘要: 首先综述了纤维复合材料(FRP)抗弯加固梁中防剥离破坏的各种措施，分析了跨中混凝土保护层的剥离破坏机理，提出一个近似计算跨中保护层剥离应力上限的方法，可供防剥离设计参考.

Abstract: The peeling failure of the concrete cover of RCbeams strengthened with fiber reinforced polymer (FRP) is analyized. Anapproximate method to estimate the upper limit of midspan peeling stress ofRC strengthened beams is proposed.
