摘要
CFRP加固混凝土桥梁是一项新的应用外粘高性能复合材料加固结构技术,本文基于国内外关于CFRP片材加固混凝土梁的理论,对加固结构中的CFRP端部应力集中规律进行计算,在此基础上分析了加固后的桥梁在车辆动载作用下端部应力的变化规律。
Reinforcing the concrete with CFRP is a new structure reinforcing technique for using the composite materials with high - performance to reinforce structure in the form of chohesion to external. Based on theories about reinforcement of concrete beam with sheet CFRP at home and abroad ,the paper has calculated the stress concentration law at ends of reinforced bridge, on this basis analyzes the changing law of stress at bridge low ends under action of vehicle mobile load.
