Strength Loading Combinations from Sec. 1605.2.1 of the 2009 IBC
Strength loading combinations from Sec. 1605.2.1 of the 2009 IBC are repeated below:
1. 1.4 (D + F)
2. 1.2 (D + F + T) + 1.6 (L + H) + 0.5 (Lr or S or R)
3. 1.2D + 1.6 (Lr or S or R) + (L or 0.8W)
4. 1.2D + 1.6W + f1L + 0.5 (Lr or S or R)
5. 1.2D + 1.0E + f1L + f2S
6. 0.9D + 1.6W + 1.6H
7. 0.9D + 1.0E + 1.6H
where f1 = 1.0 for floors in places of public assembly, for live loads in excess of 100 pounds per square foot, and for parking garage live load
= 0.5 for other live loads
f2 = 0.7 for roof configurations (such as saw tooth) that do not shed snow off the structure
= 0.2 for other roof configurations
