The macro model models the non-linear Soil Structure Interaction (SSI) for a suspension bridge anchor-block resting on frictional material. The model can be adjusted and used for other structures. The formulation uses an elasto-plastic framework to calculate the foundation response. A yield surface in the VHM (Vertical, Horizontal and Moment loading) load-space defines the failure and yield envelopes. A non-associated potential surface and a simple bi-linear hardening law describe the size of the plastic displacements. This paper make use of model parameter calibration through 2D and 3D finite element calculations. The implemented macro model routine runs with either load or displacement control, depending on the input/output required. The model is suited for integration in a program for structural design. Compared to a full finite element model, the macro model simplifies the soil structure interaction analyses significantly. The yield and potential surface includes the option to modify the shape in the H − V plane versus the M − V plane. Allowing for this flexibility in the formulation improves modelling of foundation uplift behavior.
