Modal Masses

[blackburn280]

Hello,

How can I obtain modal masses from the results of a modal analysis in SAP2000? I know values for mass participation ratios and factors as well as modal stiffness can be easily found in the output but I do not know if these are even related to modal mass.

I feel really stuck here, any help would be very greatly appreciated!

Modal masses are to be found on the same table together with the participation ratios.
