Following are the typical LRFD & ASD load combinations as per ASCE:

## LRFD

1.4(D+F) 1.2(D+F+T)+1.6(L+H)+0.5(Lr or S or R) 1.2D+1.6W+1.0L+0.5(Lr or S or R) 1.2D+1.6(Lr or S or R)+(L+ or 0.8W) 1.2D+1.0E+1.0L+0.2S 0.9D+1.6W+1.6H 0.9D+1.0E+1.6H

## ASD

D + F D + H + F + L + T D + H + F + (L, or S or R) D + H + F + 0.75 (L + T) +0.75 (L, or Sor R) D + H + F + (W or 0.72) D + H + F+ 0.75 (W or 0.72) + 0.75L + 0.75 (L, or S or R) 0.6 D + W + H 0.6 D + 0.7 E + H

D = dead load

L = live load

Lr = roof live load

W = wind load

S = snow load

E = earthquake load

R = rainwater or ice load

H = load due to lateral earth pressure, ground water pressure or pressure of bulk materials.

F = load due to fluids with well-defined pressures and maximum heights

T = Temperature load
