This tab is available when Harmonic is selected for Analysis Type in the Dynamic Analysis window.
One or more individual frequencies or frequency ranges can be specified, one to a row. CAESAR II performs a separate analysis for each frequency.
A frequency range has values for Starting Frequency, Ending Frequency, and Increment. You can enter the number of anticipated load cycles for each frequency range. Load cases are then calculated with a fatigue stress type. Otherwise, the load cases are calculated with an occasional stress type.
Harmonic loads may be specified on the Harmonic Forces Tab or the Harmonic Displacements Tab.
