A W310 x 135 with simple span of 5.0 m is used as a purlins on a roof truss inclined at 30° with the horizontal. The purlins is subject to a wind load of 4 kN/m acting perpendicular to the purlins and weight of purlins and roofing materials of 2 kN/m acting vertically. Assuming that all loads pass thru the centroid of the purlins determine ,the maximum bending stress on the purlins. Section Properties of W310 x 135 : Sx 1.86 x 106 mm³ Sy = 5.6 x 105 mm³
