mainly covers the subjects of beam design, axial forces and combined bending and axial forces,
wood structural panels, diaphragms, and shearwalls as discussed in Chapters 6, 7, 8, 9, and 10
of the textbook as well as relevant material in the 2018 NDS, NDS Supplement and 2015
SDPWS. Should you need to consult the IBC at some point, the 2018 Edition should be used.

2. Given:
The beam in the figure below has the compression side of the member
supported laterally at the ends and the quarter points. The span length
L=24 ft. The member is glulam 3-1/8 x 16-1/2 20F-V7 DF. The load is a
combination of D+L. Cand Care all equal to 1.0.

Floor joists supporting a wood structural panel floor deck are spaced at
24 inches on center. The panels are oriented with their strong direction
perpendicular to the supporting joists and are continuous over two or
more spans. Underlayment, %-in thick, is to be applied over the

sheathing. The floor dead load is 10 psf and the floor live load is 50 psf.
The total load deflection is to be less than or equal to L/360. Using the
allowable span and load tables in the 2018 IBC:

Is Table 2304.8(3) or 2304.8(5) applicable in designing the
wood structural panel deck?
What minimum span rating and thickness is required for
wood structural panel sheathing?
Do the continuous edges require support?
