Problem 7 The cantilever truss is part of vertical support system subjected to dead loads (D) and snow loads (S). The dead load is 70 psf (pound per square foot) and the snow load is 40 psf. The trusses are spaced at 20 ft apart. 1) Determine the joint vertical loads PD and PS acting on joints C, D, E, F, and G. 2) Determine the axial force in column JL due to dead load and due to snow load. 3) Determine the force in truss member JF due to dead load and due to snow load using the method of sections. 4) Using the LRFD load combinations, what it the maximum load Pu in column JL? 5) Using the LRFD load combinations, what it the maximum load Pu in truss member JF?

The cantilever truss is part of vertical support system subjected to dead loads (D) and snow
loads (S). The dead load is 70 psf (pound per square foot) and the snow load is 40 psf. The
trusses are spaced at 20 ft apart.
1) Determine the joint vertical loads PD and PS acting on joints C, D, E, F, and G.
2) Determine the axial force in column JL due to dead load and due to snow load.
3) Determine the force in truss member JF due to dead load and due to snow load using
the method of sections.
4) Using the LRFD load combinations, what it the maximum load Pu in column JL?
5) Using the LRFD load combinations, what it the maximum load Pu in truss member
JF?
