: Ensure rigid or semi-rigid diaphragms are correctly assigned. ETABS calculates story mass based on the objects associated with that specific story level and its diaphragm boundaries. Share public link etabs mass summary by story

: Understanding mass distribution can provide insights into a structure's expected performance under lateral loads.

: Floating or unattached elements will still contribute to the story mass if they are assigned to that story level, even if they do not transfer load structurally. Explain how to export this data directly to

She checked vertical mass contribution: slabs and partitions dominated, and the elevators concentrated mass at the core. The rigid diaphragm assumption held—floor masses were lumped at the diaphragm level—so any local stiffness irregularity could amplify torsion. Maya made notes: reduce eccentricity by rebalancing the core layout, or add a small shear wall on the east face to shift mass center.
