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 24/0?

A building with a non-structural interior wall is exposed to a transverse load of w = 200 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the roof diaphragm unit shear? Let L = 32 ft, a = 20 ft, b = 12 ft, be = 20 ft, and bi = 7 ft.

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 40-in. o.c. Roof dead load = 5 psf. Snow load = 51 psf. Roof sheathing is to be an APA rated plywood sheathing, and panels are to be oriented in the strong direction. The load is governed by deflection limits of L/240 for snow load and L/180 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 bending strength, Fb’. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 3,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 7,500 lbPE = 5,500 lbQD = 3,000 lbQL = 3,000 lbQLr = 5,000 lbQS = 500 lbQR = 1,000 lbQW = 0 lbQE = 0 lbSpan:L = 11 ft Member size:4 x 8 Stress grade and species:No. 1 & Better Douglas Fir-Larch Unbraced length:lu = 0 ft Moisture content:MC > 19 percent 

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member FG if PB = 1,000 lb, PC = 1,800 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 24-in. o.c. Floor dead load = 10 psf. Floor live load = 73 psf. Floor sheathing is to be an APA rated OSB Sturd-I-Floor sheathing, and panels are to be oriented in the strong direction. The load is governed by a deflection limit of L/240, 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 24 oc 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 floor system is 48-in. o.c. Floor dead load = 20 psf. Floor live load = 76 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?

A wood member is loaded as shown. Using ASD, determine the maximum axial stress in the member. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 5,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 8,000 lbPE = 5,500 lbQD = 3,500 lbQL = 3,000 lbQLr = 3,000 lbQS = 2,500 lbQR = 1,000 lbQW = 0 lbQE = 0 lbSpan:L = 13 ft Member size:4 x 14 Stress grade and species:No. 2 Douglas Fir-Larch Unbraced length:lu = L/2 = 6.5 ft Moisture content:MC < 19 percent 

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 = 72 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 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?
