In this tutorial, we perform a frequency response analysis on a truss tower to determine the effect of forces applied at different frequencies. Frequency response analyses determine the response of a design to continuous, harmonic loading, as induced by an off-balance electric motor, for example. Frequency response solutions are known as restart analyses, specifically, modal superposition. That is, they require the natural frequency and mode shape results from a previously run modal analysis of the same model.
