This tutorial video demonstrates how to apply harmonic loading to structural members in an S-FRAME model.

Harmonic loads, or cyclical loading resembling a sinusoidal pattern, represent the common dynamic forces in structures subject to vibrations due to machine loading or other cyclical loading phenomena. Used to define load cases when performing a linear or nonlinear time-history analysis, S-FRAME will calculate and display the structural response, both graphically and in tabular format, for the maximum displacement, velocity, and acceleration as well as all values at each time step.
