This report presents a detailed description of SLAM Code, a large finite element computer program to treat the two-dimensional (axisymmetric or planar) wave propagation problem through arbitrary nonlinear materials and the interaction of these motions with a flexible structure embedded within or on the soil. The basic configuration consists of a general flexible structure embedded within a soil/rock foundation composed of an arbitrary number of material layers or zones, each layer possessing its own, generally nonlinear, constitutive law. The wave propagation from the input locations into the free-field is treated by finite element methods of analysis, including the effects of nonlinear properties of the soil. An additional characteristic concerns the use of non-reflecting or ''quiet'' boundaries. These boundaries are used to limit the size of the required mesh while at the same time minimizing the effects of reflections caused by artificial boundaries of the mesh. Such characteristics are desirable when long duration responses of the structure are desired. 9 refs., 9 figs.
