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 = 3,500 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 9,000 lbPE = 7,000 lbQD = 2,000 lbQL = 2,500 lbQLr = 2,500 lbQS = 2,000 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 = L/2 = 5.5 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 16-in. o.c. Roof dead load = 8 psf. Snow load = 53 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 = 205 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 = 32 ft, b = 20 ft, and the height of the walls be 10 ft. What is the unit shear in the shear walls?

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.

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 = 19 psf. Floor live load = 105 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 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?

Determine the reference withdrawal design value, W, for a lag screw with a diameter of 7/8-in. inserted in the side grain of a wood member with a specific gravity of 0.54 where the fastener axis is perpendicular to the wood fibers.

Determine the reference withdrawal design value, W, for a smooth shank carbon steel nail or spike with a diameter of 0.12-in. driven into the side grain of a wood member with a specific gravity of 0.50 where the fastener axis is perpendicular to the wood fibers.

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 = 14 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 building with a non-structural interior wall and an opening is exposed to a transverse load of w = 210 lb/ft. Assume this load was determined from the load combinations, i.e. do not apply the load combinations to it. What is the collector force at the edge of the opening (point A)? Let L = 56 ft, a = 40 ft, b = 16 ft, be = 40 ft, and bi = 13 ft, bo = 15.5 ft.
