Abstract
Bridge fires are rare, but the damage they cause can require costly repairs or replacement. Iowa DOT decided to replace a prestressed concrete bridge after a 2019 fire, creating an opportunity to closely examine the damaged beams, or girders. After testing the structural capacity and material properties of the affected girders, researchers explored different repair methods and costs relative to replacement. The results demonstrated that visual damage does not necessarily predict structural damage, and repair may be a safe and cost-effective alternative to replacement.
