This tutorial demonstrates the modeling of vibrating machinery and its connection to a steel-skid structural system mounted to foundation piles. Modeling includes the implementation of soil damping and soil-structure interaction.

Tutorial content describes application of the following:

• Constraints which link machinery to structure

• Analytical-model meshing

• Mass sources and periodic time-history load cases

• Pile sections and connections

• Soil damping and springs

Upon conclusion of analysis, performance may be evaluated through deflection amplitudes, velocities, and accelerations, output plot function traces, and hysteretic behavior of multi-linear plastic links which correlate with dynamic-nonlinear P-Y and T-Z soil data. The tutorial PDF file, shown below, is also attached in the Attachments section.
