A beam is spaced c/c 10ft and of length 35ft and below are other details: show step by step how to do it and viz;
Roof loads
Dead
Deck =2 psf
Insulation =2 psf
Mechanical =4 psf
Ceiling= 3 psf
Roofing =14 psf
Framing= 6 psf
Live (roof) =20 psf
(Roof live load controls over snow and rain loadings)
Live load reduction is not permitted on the roof
Determine the unfactored dead load and live load on a typical interior roof beam, sketch the loading on the beam, and draw the shear and moment diagrams for the beam assuming the beam is simply-supported.
a. Distribute the specified loading assuming two-way action
b. Distribute the specified loading assuming one-way action
