Etabs Mass Summary By Story -

When you run the analysis and navigate to , you will see a table with the following key columns:

The is a tabular output in ETABS that lists the lumped mass at each story level of your model. Unlike self-weight, which is a force (kN or kips), mass is defined as Weight / Gravitational Acceleration (g) . etabs mass summary by story

: The translational mass in the X and Y directions (usually identical). When you run the analysis and navigate to

Many users assume ETABS uses the same load combinations for mass. By default, ETABS uses Dead Load (1.0) and Live Load (0.0). For seismic design, you must define a proper mass source via: Define > Mass Source > Add New Mass Source . Many users assume ETABS uses the same load

ETABS provides a powerful output table known as the which allows engineers to audit the gravity load distribution throughout the model. This article explains where to find this table, how to interpret the columns, and how to troubleshoot common discrepancies.
