Abstract: Due to their exceptional structural performance, affordability, and adaptability, prestressed concrete (PC) girders—in particular, I-shaped prestressed concrete (I-PSC) girders—have been extensively utilized in the building of bridges and other large-scale structures. However, there have been reports of I-PSC girder failures during the stressing process, which have resulted in serious project delays, monetary losses, and even fatalities. There are serious dangers to construction schedules, safety, and structural integrity when pre-stressed concrete girders fail during the stressing phase. With an emphasis on I-section pre-stressed concrete (I-PSC) girders, this study explores the fundamental causes causing these failures. Additionally, the study reveals a nonlinear relationship between elongation and applied pressure, which may indicate failure warning signs. The findings offer important new information for enhancing design procedures, quality assurance in construction, and monitoring methods to stop girder collapses in the future. It is suggested that during stressing operations, material specifications and procedural protocols be improved.
