Brief Project Description:
This project aims to investigate the residual mechanical performance of a severely-distorted steel I-girder that was exposed to a propane fireball for approximately 36-hours in Irasburg, VT on December 4th, 2023. The performance of the steel section is characterized by employing different experimental methods including geometric laser scanning, surface condition classification, dye penetrant assessment, uniaxial tension testing for mechanical properties, impact testing, chemical analysis, and metallographic analysis. The anticipated results will demonstrate the remaining structural capacity of the fire-damaged steel and provide key data for rehabilitating surface transportation infrastructure.
