Columns and shear walls span between two stories. ETABS automatically splits their mass, assigning half to the floor below and half to the floor above. Keep this in mind when comparing ETABS data to manual floor-by-floor calculations. Summary: A Better Workflow for Engineers
ETABS includes a powerful Application Programming Interface (API) that allows you to programmatically connect to your model, run analyses, and , including the Mass Summary by Story table, directly into a Pandas DataFrame or Excel . etabs mass summary by story better
: When using the "From Loads" option, ETABS automatically converts the vertical loads (Weight) into mass by dividing by g (gravitational acceleration). You do not need to perform this conversion manually. Columns and shear walls span between two stories

Columns and shear walls span between stories. ETABS automatically splits their mass—half to the story above and half to the story below. Account for this half-height allocation during manual hand-calculation comparisons. Conclusion
instead of a mass-specific unit, or confusing pounds with kips) will cause the story mass values to be off by factors of 10, 100, or even 1000. Because the story summary gives you a single, digestible number per floor, these massive scaling errors stand out immediately. Engineering Best Practices
Story Mass (UTotal) = Σ(Dead load + applicable live load) / g
