Summary of Strength Design Provisions of 2008 MSJC Code

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
