Multidimensional influence analysis on the strain–axial load relationship in U-rib welds of steel bridge decks with resin-bonded UHPC (RBPC) pavement systems

Key Points

• Strain and axial load are significantly influenced by the U-rib weld configuration in bridge decks.
• Key metrics show the effectiveness of resin-bonded UHPC in enhancing performance under various loads.
• Observational analysis was performed on steel bridge decks fitted with RBPC systems and their strain responses.
• Findings support potential advancements in design for enhanced durability and safety in steel bridge construction.
