Actual load <br />combinations include reversal of directions and swapped factors, or 8 actual cases for each LC. <br />D = Dead load <br />L = Unreduced live load <br />Ex = X-direction earthquake loading <br />Ey = Y-direction earthquake loading <br />H = Horizontal Lateral Soil Pressure <br />Sds= 1.177 (see geotechnical report) <br />ρ = 1.0 (Redundancy factor) <br /> <br />
