Hung Phi Van presents his research on Experimental and Numerical Study: Sheet Pile Abutment Systems for Water–Crossing Bridges
Advisors: Dr. Seunghee Kim and Dr. Jongwan Eun
Steel sheet pile walls are widely used for retaining walls, riverbank protection, seawalls, cofferdams, etc. While sheet piling is not designed and applied to resist vertical load, several recent studies attempted to investigate whether sheet piles could be employed for axial load-bearing. This research investigates the feasibility of these sheet piles' function as axial load-bearing foundation elements and how sheet piles can cooperate with axial and lateral loads for applying a water-crossing bridge in Nebraska. This research evaluated how axial load can influence the failure criteria of sheet piles like horizontal deflection, shear force, and moment and how lateral load can affect the vertical settlement. The prerequisites to utilize sheet pile abutments, like effective span lengths of the bridge, excavation levels, anchors systems, and soil conditions, are provided in the parametric study.
