For Concrete Structure:
v
1.4 D
v
1.4 D + 1.7 L
v
0.9 D + 1.3 (W or 1.1 E)
v
0.75 (1.4 D + 1.7 (W or 1.1 E))
v
0.75 (1.4 D + 1.7 L + 1.7 (W or 1.1 E))
v
1.4 (D + L + E)
Where D stands for total dead load i.e. D
= DL + SDEAD, L stands for live load i.e. L=LL, W stands for wind load and E
stands for earthquake load. When these seven basic load cases are combined
accordingly considering the direction of lateral loads, then according to BNBC
2006, we obtain, after simplification, the following thirty combination cases:
