Calculate the factored load using LRFD load combinations 1. Dead Load: Superimposed DL: 20 PSF plus Self-Weight TBD 2. Roof Dead Load: Superimposed DL: 10 PSF plus Self-Weight TBD 3. Live Load: First Level: 250 PSF (Assume no live load reduction.) 4. Live Load: Second Level: 100 PSF (Assume no live load reduction.) 5. Roof Live Load: 20 PSF 6. Snow Load: 25 PSF (Assume no drifting of snow) 7. Rain Load: 6-inches of standing rainwater (assume that roof drainage plan and scupper size and spacing will allow up to 6-inches of standing water on the roof during a 1-hour, 100-year storm event.) 8. Wind Load: In lieu of determining wind loading from the ASCE/SEI 7-16 wind procedure, assume a uniform wind loading of 25 PSF on the windward face of the building and 5 PSF of uniform wind loading on the leeward face (a negative (or suction effect) loading). On the roof, assume that downward wind loading will not govern on the roof, but check the roof for an uplift loading of 15 PSF of wind loading. 9. Earthquake Load: Assume that wind loading will govern for this structure. 10. Ice Load: Assume that ice loading is negligible.
