Retrofit of end stiffener jointed end sway bracing with splice plate used bearing type bolt

Abstract

One of the typical fatigue crack in welded girder of railway steel bridge is observed at the bottom of end stiffener. To repair the subsidence of bearing causing the stress concentration and the fatigue cracking at the bottom of end stiffener is burden on maintenance management. This study proposes the retrofit of end stiffener with the method with splice plate used bearing type bolt. This paper reports the results of static load test and cyclic load test conducted for evaluating the applicability of the proposed method.
