Description SSI (Soil-Structure Interaction) is part of the GeotechniCAL suite of Computer Aided Learning programs and presents a number of SSI "problems" (Walls, Embankments, Foundations, Tunnels) and within each of these there are a number of "topics" (e.g. Embedded Wall and Wall with a Berm under the Walls problem). Within each topic one can vary various system parameters (e.g. soil stiffness and structural dimensions) and examine the effects of these changes. The program incorporates quizzes to allow students or lecturers to check progress, and a tutorial in the basic operation of the software. The following data can be displayed for each case: diagram of the problem showing what can be varied; the finite element mesh; the deformed mesh; displacement vectors for the nodal points; contours of displacement and stress components; plots of horizontal and vertical displacements on horizontal and vertical lines within the mesh; plots of bending moments in structural components; plots of stress changes at the soil-structure interface (i.e. contact stresses); stress changes at points in the mesh. Perhaps more importantly, it is possible to display the results of two or more analyses simultaneously to enable comparisons (and deductions about the influences of parameter changes) to be made. The program assumes that the soil is a linear elastic isotropic material.
