Abstract:

Steel bridges are occasionally subjected to fire events ; due to accidents or explosions of vehicles containing ; flammable materials. Significant bridge fire events have ; occurred in the recent past. In order to assist with the investigation ; of damaged bridges, a method of testing has ; been developed that allows researchers to extract flange ; and web sections from a bridge girder and test them in ; real fire scenarios. The test setup allows researchers to ; examine the differences in outcomes due to a variety of ; parameters such as paint coatings on the steel, thickness ; of steel, temperature and duration of fire exposure. ; After each test, material properties may be determined ; and compared to virgin or unexposed steel and AASHTO ; specifications to see if the material properties have ; changed or if the material is below minimum standards. ; An inspection manual was developed from this testing to ; assist with diagnosing bridges after fire events based on ; visual inspections.
