The loads combinations are combinations of load cases for which the structure is designed and checked.
On this page you can find the loads combinations at serviceability limits states SLS and ultimate limits states ULS ready for using including the accidental limits states ALS, generated according to ACI 318 - 2002 considering the dead loads and varying loads (live, wind and thermal) and accidental (seismic).
Loads cases considered :
DL : dead load
LL : live load
WL : wind load
Temp : thermal effect
SEI : seismic load

Case where we have : DL & LL & WL
SLS ACI 318 - 2002
1) DL + LL
2) DL
3) DL + WL
4) DL + LL + WL
ULS ACI 318 - 2002
1) 1.2 DL + 1.6 LL
2) 1.2 DL + LL + 1.6 WL
3) 1.2 DL + 1.6 WL
4) 1.4 DL
5) 1.2 DL + 0.8 WL
6) 0.9 DL + 1.6 WL
Note
regarding the wind case, you have always to think to consider positive and negative case, means pressure/suction loading
