Load Combination Results

Combination	Type	Formula	Value (kN/m²)
Permanent (G+P)	Long-term	DL + LL	7.00
Snow (G+P+S)	Long-term	DL + LL + SL	8.00
Snow Short-term (G+P+S)	Short-term	DL + LL + SL	8.00
Wind Short-term (G+P+W)	Short-term	DL + LL + WL	8.50
Seismic (G+P+K)	Short-term	DL + LL + EL	10.00
Wind+Snow (G+P+S+W)	Short-term	DL + LL + 0.35·SL + WL	8.85
Seismic+Snow (G+P+S+K)	Short-term	DL + LL + 0.35·SL + EL	10.35

Governing Case: Seismic+Snow (G+P+S+K)

10.35 kN/m²
