Assessment and Repair of Vehicle-Fire Damage in Concrete Parking Garages

This presentation will highlight a practical approach to assess and repair concrete parking garages after vehicle fires. The methodology combines rapid field assessment with selective testing to quantify thermal effects on structural capacity and durability. Field work covers visual classification of heat-affected zones, mapping of cracking and spalls, soot removal to expose substrates, and nondestructive testing. Laboratory work includes targeted coring for petrographic examination and material testing. The paper explains when temporary shoring is warranted and recommends exploratory openings to inspect reinforcing steel and prestressed tendons in fire-affected regions. Repair strategies are presented to restore structural performance and preserve the long-term durability of garage structures after vehicle-fire events.
