3 determine the loads on the roof truss based on the tributary area and the load path.
Finding roof loading on a truss at joints chegg.
The roof truss shown is one of a series of trusses spaced 16 ft center to center.
The roof is simply supported on purlins which in turn are attached to the joints at the top chord of the truss.
0459 a snow load transfers the forces shown to the upper joints of a pratt roof truss.
For f1 8 6 and p 17 2.
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.
For simplicity neglect the distance between the roof panels and the truss members.
Neglect any horizontal reactions at the supports and assume all members are in tension.
4 determine the external reactions.
7 b supports a roof dead load of 16psf.
Cm 1 0 ct 1 0 and ci 1 0.
The truss is to be designed using seasoned f22 grade jarrah timber.
State whether each member is in tension or compression.
Self weight of the timber can be ignored in the analysis and design of the truss.
