The figure shown has trusses 6m apart with midpoint sag rods and Purtins C150x12.5 spaced 2.5m on center. The roof truss is inclined 1 vertical to 2 horizontal. The weight of roofing materials is 0.9 kPa (includes self wt.), wind load is 0.8 kPa perpendicular to the roof surface, minimum roof live load is 0.6 kPa. Consider the roofing to provide full lateral support of the purtins. Fy=345 mPa. Use the NSCP 2015 specifications.
