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 = 8,500 lbQD = 2,500 lbQL = 2,000 lbQLr = 4,500 lbQS = 3,000 lbQR = 2,500 lbQW = 0 lbQE = 0 lbSpan:L = 12 ft Member size:4 x 12 Stress grade and species:No. 1 & Better Douglas Fir-Larch Unbraced length:lu = L/2 = 6 ft Moisture content:MC < 19 percent 

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.

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 26 o.c. Does the panel require edge support? Assume the panel is 24 inches or wider.

A wood member is loaded as shown. Using ASD, determine the maximum bending 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 = 2,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 8,000 lbPE = 8,000 lbQD = 500 lbQL = 3,000 lbQLr = 1,000 lbQS = 1,500 lbQR = 2,500 lbQW = 0 lbQE = 0 lbSpan:L = 9 ft Member size:4 x 14 Stress grade and species:No. 1 & Better Douglas Fir-Larch Unbraced length:lu = L/2 = 4.5 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 rafters in a roof is 16-in. o.c. Roof dead load = 7 psf. Snow load = 58 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 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?

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building with a non-structural interior wall is exposed to a transverse load of w = 350 lb/ft. The roof is sheathed with double-layer diagonal lumber sheathing. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 36 ft, a = 30 ft, b = 6 ft, be = 20 ft, and bi = 7 ft.

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.

Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building with a non-structural interior wall is exposed to a transverse load of w = 235 lb/ft. The roof is sheathed with single-layer straight lumber sheathing. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 68 ft, a = 50 ft, b = 18 ft, be = 12 ft, and bi = 4 ft.

A wood column is pin connected at its top and bottom. Determine the controlling slenderness ratio, le/d, for the column. Assume normal temperatures, no incising, and that all loads are downward. Ignore the weight of the member.Load:PD = 3,000 lbPL = 2,500 lbPLr = 2,500 lbPS = 4,500 lbPR = 3,000 lbPW = 2,500 lbPE = 0 lbLength:L = 8 ftMember size:4 x 8Stress grade and species:No. 1 & Better Douglas Fir-LarchUnbraced length:lu = L = 8 ftMoisture content:MC < 19 percent
