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.
