If the mass summary is wrong, the building’s period (T) and modal participation ratios will be wrong.
The in ETABS is a standard output table that aggregates the distributed and point masses assigned to a building model at each floor level. It serves as a primary verification tool for structural engineers to ensure that the total seismic weight used for base shear calculations is accurate and adheres to building codes. 1. Accessing the Table
ETABS mass summary by story is a report that provides a detailed breakdown of the mass properties of a building, organized by each story or floor. The report includes various mass properties, such as:
