Etabs Mass Summary By Story [ TRUSTED · 2027 ]

Engineers use the Mass Summary to perform "sanity checks." By comparing the ETABS total mass against manual tributary area

Seismic codes (like ASCE 7 or Eurocode 8) calculate the base shear based on the total "Seismic Weight" ( etabs mass summary by story

ETABS does not simply add up the dead load. The program follows code-specific load combinations to determine seismic mass, typically: Engineers use the Mass Summary to perform "sanity checks

Analysis Results > Structure Results > Mass Summary > Mass Summary by Story 2. Understanding the Columns If not, the analyst must add more modes

After running modal analysis, ETABS provides "Modal Participating Mass Ratios." For a valid model, the sum of modal mass ratios in the X and Y directions must exceed 90% of the total mass from the Mass Summary. If not, the analyst must add more modes.
