EXPERIMENTAL STUDY ON REPAIR OF SECTION LOSS IN GIRDER END BY EXTERNALLY BONDED CARBON FIBER SHEETS USING VARTM

摘要：

　　In this study,the repair method of existing steel members has been developed using Vacuum assisted Resin Transfer Molding(VaRTM)technique.As a damaged member by corrosion,webs and vertical stiffeners in girder ends were selected.In order to study repair effect experimentally,the small-sized column models were fabricated and were repaired by externally bonded CF sheets and 3D CFRP stiffeners using VaRTM.The compressive tests were conducted for 4 kinds of specimen including the specimen with/without section loss.As a result,it was found that the load-carrying capacity of the repaired specimens by VaRTM method was restored as compared to the specimens without damage.
