Inelastic Soil-Pile-Structure Interaction under Static Loading

In this paper, inelastic pile-soil-structure interaction under static loading is presented by using finite element and boundary element methods. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear soil is modeled by using nonlinear springs along the piles. Modified Özdemir’s nonlinear model is implemented for springs and systems of equations are coupled for piles and pile groups at the interface nodes. By using this mixed type of numerical solution, it is possible to get a computationally efficient and accurate results. In order to verify the proposed formulation, the result of a full-scale load tests (performed by Rollins et al., 1996) are compared.
