Etabs Mass Summary By Story [patched] Access

Impacts the natural periods and mode shapes. 📍 Where to Find It

Add an approximate allowance for vertical columns and walls.

In structural engineering, accurately determining a building's mass distribution is critical for seismic and lateral load analysis. ETABS, the industry-standard software for building analysis and design, provides a dedicated feature to evaluate this data: the table. etabs mass summary by story

Perhaps the most critical column in the Mass Summary table is the location relative to the Center of Rigidity (CR) . While the CR is often calculated separately, the Mass Summary provides the precise location of the resultant inertial force for each floor.

: The vertical mass active in the global Z direction (only populated if vertical mass is included in your mass source). Impacts the natural periods and mode shapes

When you view the table in ETABS, you will encounter the following key parameters:

: Ensure that the Mass Source (e.g., self-weight, specified dead loads, and a percentage of live loads) is correctly calculated by the software. : The vertical mass active in the global

The resulting table provides a clear breakdown, usually organized from the highest story down to the base. Setting Up the "Mass Source" Correctly
