Abstract
Two decommissioned 80-year-old steel truss bridges were subjected to a series of nondestructive tests. The trusses had built-up members rigidly connected by rivets at the gusset plates. The floor system, many truss members and the connections exhibited considerable deterioration. The bridges were retrofitted at critical connections by welding A36 plates on the pre-A7 steel. Both bridges exhibited acceptable performance during the tests at all the limit states. In one of the bridges, failure could not be induced due to displacement limits of the loading equipment. The test results revealed that serviceability, damageability, and failure behavior of steel truss bridges possessing built-up member rigidly connected by rivets at the gusset plates are not adversely affected by local deterioration. Both the built-up members and the connections possessed adequate deformability permitting extensive redistribution. Connection retrofit by welding plates was feasible and successful.
