000015833 520__ $$2eng$$aDynamic soil-structure interaction problems are usually solved by a sub-structuring technique where the soil-structure system is decomposed into two sub-domains: the nonlinear superstructure and the linear visco-elastic unbounded soil. The superstructure might include, in addition to the actual structure, a part of soil showing a nonlinear behaviour. To address this problem, a BEM-FEM coupling strategy is adopted in this work. On one hand, the superstructure is modelled by a FE method which allows to take into account nonlinear constitutive laws as well as complex geometries in a straightforward way. Besides, the problem within the superstructure is formulated in the time domain. On the other hand, the interaction forces coming from the linear unbounded soil are represented by means of an impedance operator defined on the soil-superstructure interface and computed with a Laplace-domain BE method. A semi-industrial application is used to illustrate the effect of nonlinear soil (the Hujeux law) in soil-structure interaction analysis.
