Abstract

In this study, the use of high performance vises are proposed as two easy and temporal repair methods of repairing fatigue cracks in steel bridge members. These repair methods could temporarily decrease crack growth rate until executing permanent repair works. In this paper, to investigate the repairing effect of crack growth by the proposed methods, fatigue crack growth tests and FE analysis for MT and steel girder specimens were carried out. These results showed the proposed method could control the crack growth rate.
