The Mass Summary by Story is a report table that lists the translational seismic mass (UX, UY, and UZ) for each story in your building model. It is calculated based on the Mass Source you defined in your model, making it the authoritative report for seismic weight distribution.

Alternatively, you can access this via the top menu by clicking . Key Column Definitions

By mastering the Mass Summary table, you move from simply "running the model" to truly understanding the behavior of your structure. etabs mass summary by story

: The specific level of the building (e.g., Story1, Story2, Roof). Ux : The total mass activated in the global X-direction. Uy : The total mass activated in the global Y-direction.
