Assessment, Repair and Replacement of Bridges Subjected to Fire

Recently, a bridge on I-29 near Sioux City, IA caught fire causing various levels of damage to multiple prestressed girders. Visual inspection and load testing of the bridge were completed to aid in the development of a response. However, the lack of available information on fire damage created a situation where the decision makers were left without many tools or guidelines to follow for such cases. Research to develop guidelines is needed. This research will assess the condition and structural behavior of precast pre-stressed concrete fire-damaged bridge girders. Additionally, repair, and replacement options will be explored.
