Mass Participation (Normalized)
You can list mass participation ratios in the global X, Y, and Z directions
normalized with respect to the total mass after running a frequency study.
Mass participation ratios are important in determining the adequacy of
the calculated modes to solve dynamic problems with base motion. Many
codes require that at least 80% of the mass of the system participates
in specified directions.
To list mass participation factors:
Run a frequency or a linear dynamic study.
Right-click the Results
folder and select List Mass Participation.
The Mass
Participation (Normalized)
dialog box opens.
Click Save to
save the listed information to an Excel
