Understanding the ETABS Mass Summary by Story In structural engineering, specifically when performing seismic or dynamic analysis, the distribution of mass is just as critical as the stiffness of the members. ETABS provides a dedicated output called the to help engineers verify that their model’s inertia is correctly accounted for.

: Includes user-assigned point, line, or area masses for non-structural elements like cladding or partitions. : Includes user-assigned point, line, or area masses
The table typically includes the following columns for each story: : The specific floor level.
⭐ The Mass Summary is your model's "scale." If the numbers look off, your seismic results will be too. If you'd like to refine this for a specific audience: Tell me your target reader (student vs. senior engineer) Specify if you want a step-by-step tutorial Provide a preferred word count
These should generally be equal unless you have strange property modifiers. This represents the total translational mass per floor.
