When Garage Floor analysis is enabled, the uniform live load is replaced by loading to simulate a car. A pair of spaced 2000 lb. concentrated point loads are tested in the worse case locations that maximize moment and shear. They are spaced 5'-0" or 8'-0‖ nominally on center, depending on vehicle orientation vs. joist direction.
- one-car garages only
- joist spacing must be 16" on-center or less
no cantilever spans
When used, the Design Report includes an "GF*" load case and a Note describing the analysis. See the Design Report for additional notes and cautions.
