The horse stall has a flat roof with a slope of 80 mm/m. It is located in an open field where the ground snow load is 1.20 kN/m^2. Determine the snow load that is required to design the roof of the stall. A hospital located in central Illinois has a flat roof. Determine the snow load m kN/m^2 that is required to design the roof. Solution given that ground snow load (G) = 1.2 kN/m 2 For low value house exposer factor (E) = 0.7 Thermal Factor T = 1 if not given Roof Slope Factor R = (70 - X)/(70 - Y) <= 1 where X equals the angle in degrees, and Y varies by roof type: X= arctan(80/1000)= 4.574 let roof type is B R= (70-4.574) /(70-30) > 1 Hence R= 1 roof snow load RSL = 0.7 * G * E * T * R = 0.7*1.2*0.7*1*1= 0.588 KN/m 2 .
