Summary By Story Better ((link)): Etabs Mass

: If your model uses diaphragms, also include the Center of Mass and Rigidity table to show eccentricity. 3. Verification & Quality Checks

Check that the mass values are in the correct units (e.g., kilograms or tonnes); ETABS may require manual conversion (dividing by gravity if using weight units) 3. Torsional Sensitivity (CM vs. CR) For a superior report, include the Centers of Mass and Rigidity table to identify eccentricity Table Path: etabs mass summary by story better

Ensure you haven't modeled a slab over a slab, which doubles the mass in that specific story. : If your model uses diaphragms, also include

The most common mistake is neglecting how ETABS calculates mass. By default, ETABS does not automatically know what to weigh. You must define a ( Define > Mass Source ). Torsional Sensitivity (CM vs
