FRP筋体外预应力混凝土梁的疲劳性能研究
Research on Fatigue Performance of FRP Externally-Prestressed RC Beam
【摘要】 随着FRP筋体外预应力技术在桥梁建设、结构加固等方面的应用逐步增大,有必要对于FRP筋体外预应力混凝土梁的疲劳性能进行研究.在试验的基础上,对该种结构的疲劳损伤机理与疲劳寿命预测进行了研究分析,并提出了抗疲劳设计的若干建议.
【Abstract】 With the increasing application of FRP(fiber-glass-reinforced plastic) external prestress in the bridge construction and structural reinforcement,it is necessary to carry out research on the fatigue performance of the FRP externally-prestressed RC beam.On the basis of practical tests,this paper makes research on the fatigue damage mechanism and fatigue life prediction of the structure,and presents suggestions for the fatigue-resistant design.
