Assume a 5-story steel frame in a high-seismic zone.

Select . (This is the most common way to see story-by-story mass).

This is the rotational mass (polar moment of inertia) about each axis.

In the realm of computational structural engineering, the "Mass Summary by Story" table is not merely a ledger of weights; it is the quantitative biography of the building. While ETABS provides a plethora of complex output displays—from moment diagrams to shell stress contours—the Mass Summary remains the fundamental diagnostic tool for verifying the physical integrity of the analytical model. It serves as the bridge between the architectural intent and the structural reality, translating volumetric geometry into the inertial forces that govern seismic response.

The mass summary by story is a vital tool for structural engineers, as it helps them understand the distribution of mass within the building. This information is essential for several reasons:
