000020300 520__ $$2eng$$aThe consideration of soil-structure interaction in linear and nonlinear regime relies on different methods of analysis in seismic design studies. This paper is dedicated to the assessment of various methods for modeling soil-structure interaction in order to define their validity range within seismic design projects in Civil Engineering. Particular emphasis is given on the nonlinearity that is developed along the soil-structure interface (foundation uplifting). The validity range of each method is examined with respect to both the intensity level of seismic action and also some quantities of interest characterizing the response of a typical soil-structure system, such as the uplift ratio of the foundation, the floor spectra developed in representative points within the structure and the demand for reinforcement steel in characteristic sections. Based on the study of a configuration pertaining to a typical industrial building embedded in a homogeneous soil and described by a set of dimensionless parameters, a comparison is performed to identify the relevance and conservatism of each analysis method. Specifically, the study examines pseudo-static and time-history approaches based on the spring method and a FEM-BEM coupled approach.
