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 12-in. o.c. Roof dead load = 10 psf. Snow load = 73 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 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 = 315 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 = 40 ft, b = 22 ft, and the height of the walls be 8 ft. The walls are sheathed with conventional diagonal sheathing. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

Determine the reference withdrawal design value, W, for a lag screw with a diameter of 5/16-in. inserted in the side grain of a wood member with a specific gravity of 0.60 where the fastener axis is perpendicular to the wood fibers.

Use APA D510 Panel Design Specification to answer the following question. What is the predominant performance category that corresponds to APA Rated Sheathing with a span rating of 32/16?

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member GH if PB = 1,100 lb, PC = 1,600 lb, PD = 3,100 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

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 = 215 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 = 36 ft, b = 24 ft, and the height of the walls be 9.5 ft. The walls are sheathed with blocked particleboard. Are the shear walls satisfactory in regard to the maximum shear wall aspect ratio?

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building is exposed to a transverse load of wU = 500 lb/ft due to wind. Assume this load was determined from the ASD load combinations, i.e. do not apply the load combinations to it. The wood structural panel is 7/16-in. thick 24/16 span-rated sheathing blocked. Nails are 8d common and spaced every 6 in. at diaphragm boundaries and all panel edges utilizing a single row of nails. Is this design adequate for the transverse load? Let L = 42 ft and b = 30 ft.

A nailed shear connection is fabricated with 3/4-in. bolts and lumber that has a moisture content of 19 percent. The lumber remains above 21 percent while the connection is in service. What wet service factor, CM, should be used?

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 12-in. o.c. Floor dead load = 17 psf. Floor live load = 148 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 Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building is exposed to a transverse load of wU = 425 lb/ft due to wind. Assume this load was determined from the ASD load combinations, i.e. do not apply the load combinations to it. The wood structural panel is 7/16-in. thick 24/16 span-rated sheathing blocked. Nails are 8d common and spaced every 6 in. at diaphragm boundaries and all panel edges utilizing a single row of nails. Is this design adequate for the transverse load? Let L = 60 ft and b = 40 ft.
