Determine the bending Fbx+ reference design value for 24F-1.7E softwood glulams.

Use APA Technical Note Q225 entitled Load-Span Tables for APA Structural-Use Panels and ASD procedures to answer the following question.The spacing of joists in a floor system is 36-in. o.c. Floor dead load = 18 psf. Floor live load = 96 psf. Floor sheathing is to be an APA rated OSB sheathing, and panels are to be oriented in the strong direction. The load is governed by bending and shear for total load. Only consider these limits. Assume multi-span, normal duration of load, dry conditions, and panels 24 inches or wider. Would a panel with a span rating of 40/20 be adequate?

Use the AWC Manual for Engineered Wood Construction, 2018 Edition to answer the following question. An APA Rated Sheathing panel with a span rating of 24/16 is used with framing that is spaced at 18 o.c. Does the panel require edge support? Assume the panel is 24 inches or wider.

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member GH if PB = 900 lb, PC = 2,000 lb, PD = 2,800 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.
