100 psf live load at second floor lobby
100 psf live load at second floor lobby
(OP)
Asce 7-05 and IBC both call out for a live load of 100 psf at lobbies and first floor corridors. Is the lobby being referred to here for all floors? I generally design all upper floors of office buildings for a live load of 80 psf. You could have a large lobby area around an elevator shaft, should I design this area for 100 psf (may or may not know the lobby size if it is a shell space)? Another unknown on shell space is assembly areas. Say the owner puts in a large conference room, would you consider that an assembly loading and require the 100 psf loading. What size area would warrant assembly loading in an office building?

Agreed. You run the numbers on some of these live loads and it's like a bunch of heavy folks packed in there like sardines.....but I try not to take any chances.
