不同加固方式对钢筋混凝土梁抗弯性能的影响
Effect of Different Reinforcement Methods on the Bending Performance of Reinforced Concrete Beams
摘要
Abstract
3 test beams through the scale model which was based on the prestressed reinforced concrete beam in the construction of a highway in China was designed .The effects of CFRP ( Carbon Fiber Reinforced Plastics ) sheet reinforcement and prestressed steel strand reinforcement on the bending performance of bridge were studied , through analyzing the changes of the limit bearing capacity of girders, the deflection of the beam body , the strain of concrete , reinforcement and reinforcing materials , the number and development of cracks . The results show that: CFRP sheets reinforcement and prestressed steel strand reinforcement can improve the bearing capacity of beams effectively ;CFRP sheets reinforcement can limit the development of cracks by disperse the tensile stress of concrete .Prestressed steel strand reinforcement can bind the bending of the beam obviously , as well as reduce the deflection effectively .关键词
