EXTENDED HYPERBOLIC MODEL FOR SAND-TO-CONCRETE INTERFACES
A relatively simple, 4-parameter extended hyperbolic model for interfaces was developed for use in soil-structure interaction analyses. The model accommodates arbitrary stress path directions and includes 3 key elements: 1) development of a yield surface during interface shear; 2) a formulation for yield-inducing shear stiffness that is applicable to any stress path orientation; and 3) a formulation for unloading-reloading shear stiffness. The model was evaluated against the results of shear tests performed at the interface between 3 different types of sand and a concrete surface under a variety of stress paths. Comparisons between measured and calculated interface response indicate that the model provides accurate estimates of the response of sand-to-concrete interfaces.
