Abstract


High-strength bolt damage in steel truss bridge connections is often difficult to detect early due to the lack of routine inspections. This study aims to analyze the failure patterns of high-strength bolts Grade 8.8, Grade 10.9, and A325 after tensile testing and to evaluate their implications for bridge inspection strategies. Tests were conducted using a Universal Testing Machine with a minimum of three specimens for each grade. The results show that Grade 8.8 and Grade 10.9 bolts failed by thread stripping, whereas A325 bolts fractured in the shank. The thread stripping pattern of Grade 8.8 and Grade 10.9 bolts has the potential to be more easily detected visually at an early stage compared to the sudden fracture of A325 bolts. These findings support the importance of routine bridge health inspections in accordance with applicable guidelines so that loose bolts can be replaced before connection failure occurs.
