<p>Though most of buckle plate girders for steel railway bridges have been in existence for about a century since their constructions, it is often preferable to prolong their lives considering such as their narrow construction space. Some situations exist where cracks generate in buckle plates. The conventional repairing method for this crack has problems in terms of its workability and economy. In this study, first of all, the load-bearing characteristics of a buckle plate with crack of some length were clarified by the laboratory load test and the FE analysis. Next, based on the result, the simple repairing method against the crack was developed and its effect was verified.</p>
