3. Select a W6 purlin for a roof system whose trusses are 5m on center and sag rods are used at the third points between trusses. The span of the truss is 15m, purlin spacing is 1.4m, and the height of truss is 3.6m. Full lateral support is supplied by the roof above. Use Fy = 350MPa and LRFD method. The following loads are in terms of kilonewtons per square meter of roof surface. Roofing = 0.30kPa Wind pressure = 0.75kPa Roof live load = 0.60kPa.
