The truss in fig. The roof is simply supported on purlins which in turn are attached to the joints at the top chord of the truss. Cm 1 0 ct 1 0 and ci 1 0. Fasteners do not reduce the area off the members.

7 b supports a roof dead load of 16psf. The roofing panels span between purlins see loads and load paths lab notes which carry the roof loads to the truss joints. Point loads f1 and f2 applied at joint 1 2 and 3 represent the permanent and imposed loads on the truss respectively where the imposed load is occupancy live load. Self weight of the timber can be ignored in the analysis and design of the truss.

For simplicity neglect the distance between the roof panels and the truss members. 0459 a snow load transfers the forces shown to the upper joints of a pratt roof truss. State whether each member is in tension or compression. The roof truss shown is one of a series of trusses spaced 16 ft center to center.
