The beam on nonlinear Winkler foundation (BNWF) model is widely used in soil–structure interaction (SSI) analysis owing to its relative simplicity. This paper focuses on the development of a versatile dynamic BNWF model for the analysis of shallow and deep foundations. The model is developed as a stand-alone module to be incorporated in commercial nonlinear structural analysis software. The features of the model discussed are the loading and unloading rules, slack zone development, the modeling of cyclic degradation and radiation damping. The model is shown to be capable of representing various response features observed in SSI experiments. In addition, the predictions of the model for centrifuge tests of piles in weakening and partially weakening soil are shown to be in good agreement with the experimental results. This agreement demonstrates the potential of the model as a useful tool for design engineers involved in seismic design, especially performance-based design.

Interaction Problem

When the behaviors of the structures under the earthquake effect are examined, they are assumed as fixed foundation. Since the differentiation of the soil characteristics effects the behavior of the structures, the soil structure interaction should be taken into account in the earthquake analyzes. The main objective of this research is to examine the soil structure interaction. In this research, the masonry structure with two stories constructed from the stone material is handled. In addition to this, the soil is taken into consideration as sand, clay, rock, and fixed support. The masonry structure with two stories and the different soil layers have been modeledthree-dimensionally by with SAP 2000 program. In the scope of research, Kobe ground motion data was applied to the soil-masonry structure systems by using time history method in the analysis.

Interaction Problem

Abstract An asymmetric mine-soil-structure interaction problem with two competing plate thicknesses was modeled using a hydrodynamic code. The plate acts as a momentum trap for a vertical impulse test facility proposed at the Aberdeen Proving Ground. The model allows simulation of complex asymmetric explosive-soil-structure interaction effects and generates loading and response of the plate due to varying center line offset, stand-off, depth of soil overburden and explosive contents. The objective is to select a minimally thick plate which must survive the interaction without any significant residual permanent deformation.
