Etabs Mass Summary By Story Better -

A junior engineer noticed the Mass Summary by Story showed only 1,200 kips of mass at the ground floor, while the architectural takeoff showed 1,800 kips.

If you have ever run a seismic analysis in ETABS, you have undoubtedly stared at the Mass Summary by Story 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. etabs mass summary by story better

Is the mass correct? Did the software double-count the dead load? Why is the seismic weight different from the gravity takeoff? And most importantly— how can you get a better, more reliable Mass Summary? A junior engineer noticed the Mass Summary by
