My office has a questions regarding floor deflections:
We have a building where, due to wall layouts, we are not able to run columns continuously to the foundation in one area. Therefore, in this area we have a column supported by a beam on the 2nd floor.
My question is this: When looking at the deflection of the beams on the 3rd floor that are supported by this column, for code purposes, do we have to add the deflections from the 2nd floor support beam, to the individual beam deflections on the 3rd floor? This particular case is an interior column. The ceiling below is a drop ceiling. Based on my condition, I dont think I would need to do this, but are there any conditions where this would be appropriate? (Say at an exterior wall with a large window supported by the 3rd floor beam).
