EQ FORCE STARTING LEVEL

[hsn199]

Hey, I wanna ask at what level Shall EQ be inputted in ETABS? Starting from the base or starting from the ground floor? Cuz I've been told from the GF, and this frankly isn't convincing... Any help?

The location of the base depends on several factors. Structures Magazine has an article, "Location of Base for Seismic Design", that discusses this:
