TR.37.6 Steady State and Harmonic Analysis

This section describes how to define steady state analysis in STAAD.Pro.

Note: This requires a STAAD.Pro Advanced Analysis license.

TR.37.6.1 Purpose
TR.37.6.2 Define Harmonic Output Frequencies
If Harmonic is requested above, then optionally include the next input.
TR.37.6.3 Define Load Case Number
The load case which contains the MODAL CALC command is automatically used for the load case number.
TR.37.6.4 Steady Ground Motion Loading
This set of commands may be used to specify steady ground motion loading on the structure, the ground motion frequency, the modal damping, and the phase relationship of ground motions in each of the global directions.
TR.37.6.5 Steady Force Loading
This set of commands may be used to specify JOINT loads on the structure, the forcing frequency, the modal damping, and the phase relationship of loads in each of the global directions.
TR.37.6.6 Harmonic Ground Motion Loading
This set of commands may be used to specify harmonic ground motion loading on the structure, the modal damping, and the phase relationship of ground motions in each of the global directions.
TR.37.6.7 Harmonic Force Loading
This set of commands may be used to specify JOINT loads on the structure, the modal damping, and the phase relationship of loads in each of the global directions.
