In ETABS, the is one of the most critical outputs for structural engineers. It provides a concise breakdown of how weight is distributed across the height of a building—a factor that directly dictates seismic forces and dynamic behavior.
Once you have run your analysis, follow this path to find the data: Display > Show Tables etabs mass summary by story
Seismic codes (like ASCE 7 or Eurocode 8) calculate the base shear based on the total "Seismic Weight" ( In ETABS, the is one of the most
Accidental double-modeling of slabs or beams. A quick glance at the cumulative mass helps
A quick glance at the cumulative mass helps verify if you are working in kips, tons, or kilograms. C. Calculating Eccentricity
For professional design reports, you can right-click the table and select . This allows you to create charts showing the mass distribution over the building height, which is a great visual aid for client presentations or calculation packages.
