Problem 5.13

Repeat Prob. 5.11 except the member is a 24F-V4 Douglas Fir-Larch glulam.

Prob. 5.11

Given:
 Douglas Fir glulam is used to span 32 ft, carrying an ASD load combination of (D S). The load is a uniform load over a simple span, and the beam is supported so that buckling is prevented.

Find: a. Sketch the beam and the cross section. Show calculations to verify the section properties Sx and Ix for the member, and compare with values in NDS Supplement Table 1C. b. Determine the adjusted ASD values associated with the section properties in part a. These include Fbx + Fux and Fx c. Repeat part b except the moisture content of the member may exceed 16 percent.
