STUDY ON THE REPAIR METHOD FOR CORRODED STEEL GIRDER END BY USE OF PULTRUDED FRP ANGLE SECTIONS

Abstract

 In this study, a repair method of corroded steel girder end by using pultruded hybrid FRP angle sections is proposed. To examine performance recovery by using the proposed repair method, steel girder end specimens with thickness reduced portions were repaired by bonding hybrid FRP angle sections with and without FRP bolts, and compression tests were performed on these specimens. Results showed that the compressive bearing capacity of repaired specimens were recovered to the level equal to or more than that of the intact steel girder end specimen.
