The Pratt roof trusses are uniformly spaced every 4.5m. The deck, roofing material, and the purlins have an average weight of 0.28kN/m2. The building is located in New York where the anticipated snow load is 1.0kN/m2 and the anticipated ice load is 0.4kN/m2. These loadings occur over the horizontal projected area of the roof. Determine the force in each member due to dead load, snow, and ice loads. Neglect the weight of the truss members and assume A is pinned and E is a roller.

Composite Construction

Composite construction is the construction of structures in which two or more materials are used. Regarding structural engineering, composite construction is a construction where two materials are bound together in a technical manner such that both the materials act as a single unit to carry and transfer the load. The motives of composite construction are to increase the structural strength, make structures more aesthetic, and provide a sustainable environment.
