| Abstract: | Theoretical analysis and experimental analysis are combined to investigate the crack resistance of pre-splitting reinforced concrete beams strengthened by the CFRP cloth.the crack law of development and the crack contributory factor of the reinforced concrete beams in the short-term load are discussed, the calcuiating mode of the average crack width and the maximum crack width are analyzed on the reinforced concrete beams in the short-term load.All of those are very useful to revise the CFRP reinforcement technology standard, consummates the method of reinforcement designing and develop the reinforcement technology in the future. |
