Check if you applied property modifiers (like 0.0 weight) to certain elements.
: Improper auto-meshing of walls or slabs can lead to incorrect mass calculations. Manual meshing is often recommended for higher accuracy. Accessing and Exporting the Report To generate and review this data for your project report: Additional Mass Frame Objects etabs mass summary by story better
ETABS only includes mass for elements physically modeled. If you have a heavy parapet, signboard, or mezzanine drawn as a line load—did you convert it to a mass? Model heavy non-structural components as point masses ( Assign > Shell/Area > Additional Mass ). Check if you applied property modifiers (like 0
In structural engineering, precision in mass distribution is the bedrock of reliable seismic analysis. While ETABS offers various ways to view model data, the Mass Summary by Story Accessing and Exporting the Report To generate and
