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.

A building with a non-structural interior wall and an opening is exposed to a transverse load of w = 285 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 = 44 ft, a = 30 ft, b = 14 ft, be = 30 ft, and bi = 10 ft, bo = 12.5 ft.

Determine the reference withdrawal design value, W, for a lag screw with a diameter of 1-1/8-in. inserted in the side grain of a wood member with a specific gravity of 0.67 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 flat roof is 16-in. o.c. Roof dead load = 9 psf. Snow load = 67 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 seismic load of wU = 280 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 = 20 ft, and the height of the walls be 10 ft. The walls are sheathed with 5/8-in.-thick particalboard sheathing and 10d nails spaced every 6 in. around the panel edges. Is this design adequate for the load?

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 = 36 ft, a = 30 ft, b = 6 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 rafters in a roof is 36-in. o.c. Roof dead load = 7 psf. Snow load = 38 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?
