Question
Determine:
1. The interior and end panel point loads and reactions on the truss
2. The maximum tension force and maximum compression force in the diagonals, (and
identify which they are).
3. The maximum tension force and maximum compression force in the verticals, (and
identify which they are).
4. The maximum tension force and maximum compression force in the chords, (and
identify which they are).
5. Using a square cross-section (b = h, I = b*/12)of a material with an allowable stress
of 15 ksi, and a Young's modulus of E = 2,000,000 psi, size the "worst-case" top
chord, bottom chord, diagonal and vertical for crush and bending to the nearest
inch. Use a factor of safety for crush of 1.67, and for buckling of 1.9,
6. If you REMOVE the vertical DK, resize the worst-case top chord and compare it to
your previous answer...
Total distributed load = 240k. Span = 96', depth = 12'. Hybrid configuration of verticals
and diagonals.
