Displacement Capacities of H-Piles in Integral Abutment Bridges
Integral abutment bridge (IAB) length is limited by the lateral displacement capacity of the piles supporting the bridge. This paper presents a numerical study calibrated to experimental tests to investigate the lateral displacement capacity of H-piles (HPs) in integral abutment bridges subjected to combined axial load and cyclic displacement amplitude. Eleven steel HP sections with two axis orientations (weak and strong) commonly used in IAB construction practice were investigated. Several soil types surrounding the piles were examined to investigate the effect of soil stiffness on displacement capacity. Buckling displacement capacity was found to be an average of 3 and 1.5 times the plastic moment capacity for weak and strong axis bending, respectively. It was revealed that soil stiffness has a significant impact on the onset of local buckling of the piles. Based on computed pile displacement capacities, the maximum length of integral abutment bridges was estimated and compared with the current practice of US departments of transportation.
