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 40/20 is used with framing that is spaced at 34 o.c. Does the panel require edge support? Assume the panel is 24 inches or wider.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A single-story wood-frame building is exposed to a wind load of wU = 350 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 68 ft, b = 22 ft, and the height of the walls be 9 ft. The walls are sheathed with blocked wood structural panels. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

A single-story wood-frame building is exposed to a wind load of wU = 220 lb/ft. For simplicity, assume this load was determined from the load combinations, i.e. do not apply the load combinations to it, and that the building has no windows or doors. Let L = 44 ft, b = 30 ft, and the height of the walls be 10 ft. What is the unit shear in the shear walls?

Bolts should never be forcibly driven.

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member GH if PB = 1,000 lb, PC = 1,400 lb, PD = 2,800 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

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 30-in. o.c. Floor dead load = 18 psf. Floor live load = 144 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 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 flat roof is 24-in. o.c. Roof dead load = 10 psf. Snow load = 70 psf. Roof sheathing is to be an APA rated plywood STRUCTURAL I sheathing, and panels are to be oriented in the weak direction. The load is governed by deflection limits of L/360 for snow load and L/240 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 32/16 be adequate?

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 rafters in a roof is 16-in. o.c. Roof dead load = 12 psf. Snow load = 39 psf. Roof sheathing is to be an APA rated plywood STRUCTURAL I sheathing, and panels are to be oriented in the weak direction. The load is governed by deflection limits of L/360 for snow load and L/240 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 32/16 be adequate?

A wood member is loaded as shown. Using ASD, determine the adjusted tension strength, Ft’. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 1,500 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 7,000 lbPE = 7,500 lbQD = 500 lbQL = 3,500 lbQLr = 4,500 lbQS = 1,000 lbQR = 3,500 lbQW = 0 lbQE = 0 lbSpan:L = 14 ft Member size:4 x 10 Stress grade and species:No. 2 Douglas Fir-Larch Unbraced length:lu = L/2 = 7 ft Moisture content:MC > 19 percent 

If a column is loaded to failure, buckling will occur about the axis that has the largest slenderness ratio.
