The default ETABS Mass Summary is only as good as your assumptions. Many engineers open the table, see a number, and immediately proceed to design. This is a mistake.

ETABS calculates mass as (Load Cases assigned as mass source) / g (acceleration due to gravity). By default, ETABS may only include self-weight and superimposed dead loads. It often ignores :

) to obtain true mass, or adjusting units (e.g., dividing by 1,000) for standard reporting. 4. Verification Checklist Center of rigidity - ETABS - CSI Knowledge Base

If you have ever run a seismic analysis in ETABS, you have likely stared at the table. It appears innocent enough: a simple spreadsheet showing mass, weight, and lateral stiffness. But for experienced structural engineers, the default output often raises more questions than it answers.
