Abstract
The main reason of deterioration in a steel girder is corrosion. Because the characteristic of Carbon Fiber Reinforced Polymer (CFRP) is light weight, high strength and high durability, CFRP has been paid to attentions for repairing or reinforcing the steel bridge. Although many studies on the application of CFRP to the steel bridge have been reported so far, previous studies mainly focus on axial or bending members. However, most of the corrosion in the steel bridge is found on webs near the end of the girder. There has been few investigated on repairing or reinforcing the web using CFRP. Therefore, shear buckling test for steel girder bonded CFRP sheets on the web is carried out in this study. In the test, CFRP sheets are bonded on the web through low elastic putty layer in order to improve the ductility for out-of-plane large deformation under shear. Furthermore, an evaluation method of its ultimate strength is proposed by modifying the Basler's equation.
