Finite Element Analysis of the Lateral Load Test on Battered Pile Group at I-10 Twin Span Bridge

The objectives of this research study are to develop a three-dimensional finite element model to simulate the lateral behavior of battered pile group foundations, and verify the model using the results of a unique static lateral load test that was conducted at I-10 Twin Span Bridge; investigate the lateral behavior of battered pile group foundations subjected to static loads as compared to vertical single and pile group foundations; investigate the lateral behavior of battered pile group foundations subjected to dynamic loads due to barge impact; develop p-y curves for different soil types for use in the analysis and design of battered pile group foundations subjected to lateral loads; develop guidance to select parameters and p-y curves for application in FB-MultiPier, Midas and CSIBRidge/SAP2000 software’s; develop rationale values of p-multipliers to incorporate the group effect in the design and analysis of battered pile group foundations subjected to lateral loads; and to evaluate the contribution of axial loads carried by battered piles.
