A 24F-V4 Douglas Fir-Larch glulam is used to span 32 ft, carrying an ASD load combination (D + S). The load is uniform over a simple span, and the beam is laterally supported so that lateral torsional buckling is prevented.
1. Sketch the beam and the cross section. Show calculations to verify the section properties Sx, and Ix for the member, and compare with the NDS Supplement Table 1C.
2. Determine the adjusted ASD values associated with the section properties in part 1. These include Fbx+’, Fvx’ and Ex’.
3. Repeat part 2 except the moisture content (MC) of the member exceeds 16%
