• 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.
