![PROJECT PROBLEM. The Pratt roof trusses are uniformly spaced every 4.5 m. The
deck, roofing material, and the purlins have an average weight of 0.28 kN/m² .
The building is located in Metro Manila where the anticipated rain load is 0.40
kN/m?. These loadings occur over the horizontal projected area of the roof.
Determine the force in each member due to dead load, and rain loads. Neglect
the weight of the truss members and assume A is pinned and E is a roller.
