D ₌ dead load
E ₌ earthquake load
E_h = effect of horizontal seismic forces
E_m = seismic load effect, including overstrength
E_mh = effect of horizontal seismic forces, including overstrength
E_v = vertical seismic effect applied in the vertically downward direction
L ₌ live load
L_{r =} roof live load
R ₌ rain load
S ₌ snow load
U ₌ strength of a member or cross section required to resist factored loads or related internal moments and forces in such combinations as stipulated in ACI 318-19
W ₌ wind load

...

The required strength of a member U is controlled to at least equal to the effects of factored loads in ACI Table 5.3.1. Internal forces and moments resulting from the load combination are expressed as the required strength for the design.
