D = Dead load
E_m = Combined applied design force on the horizontal and vertical seismic load effects
E_mh= The effect of horizontal seismic forces, including overstrength
L = Live load
L_r = roof live load
S = snow load
W = Wind load
E_v = Vertical seismic load effect

When a structure is subject to seismic load effects, the following load combinations is are applied in addition to the basic combinations and associated Exceptions in Section 2.4.1. E =f(E_v; E_h) (defined in Section 12.4.2) is combined with the effects of other loads, ; the following seismic load combinations is applied.Image Removedare applied.

• 1.0D + 0.7E_v + 0.7E_h

• 1.0D + 0.525E_v + 0.525E_h + 0.75L + 0.75S

• 0.6D - 0.7E_v + 0.7E_h

Where the seismic load effect with overstrength, E_m = f(E_v; E_mh), defined in Section 12.4.3, is combined with the effects of other loads.
