If a concrete wall extends through a slab, ETABS can double-count the mass at the intersection unless meshing is perfect. The default summary hides this error. : Improper auto-meshing of walls or slabs can
If you have ever run a seismic analysis in ETABS, you have undoubtedly stared at the table. It appears deceptively simple: a list of stories, masses in X, Y, Z, and a summation. Yet, for many engineers, this table is a source of quiet anxiety. The default summary hides this error
: It helps identify if Superimposed Dead Loads (SDL) on null areas are failing to transfer to the seismic mass because a diaphragm wasn't assigned.
