• Abstract:
  This study was carried out to evaluate fatigue cracking in tie plates in a multi-span, non-redundant, steel plategirder ; bridge. The plates are needed to provide continuity for the transverse floor beams. Repairs have been ; on-going, and the goal was to explain the cause of cracking and provide guidelines for those responsible for ; designing the repairs to assure that there would be no further cracks. The designers expected that these bolted ; plates would act in simple tension, which is a reasonable assumption based on the plans and actual bridge. ; Field monitoring has demonstrated however that the plates are acting as bending members, with bending ; occurring in the horizontal plane. The field testing, combined with a finite element analysis, have been used to ; explain the behavior causing bending and to provide guidance on how best to make the repairs.
