Loss of cross section due to corrosion is a main factor in deterioration of steel bridges. Therefore, carbon fiber reinforced plastic (CFRP) is paid to attentions for repairing and reinforcing the steel bridges since CFRP is light weight, high strength and high durability. Although many researches relating to this topic have been reported so far, previous researches mainly focused on the application of CFRP to axial or bending members. On the other hand, most of the corrosion is found on web at the end of main girders. Investigations on repairing and reinforcing corroded web using CFRP have been reported few. In this research, shear buckling test for steel girder bonded by CFRP sheets on web is carried out. Low elastic putty layers are inserted between steel and CFRP sheets in order to improve the performance of out-of-plane deformation. An evaluation method of shear strength of the girder is also proposed. |
