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 = 41 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?

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 19.2-in. o.c. Roof dead load = 15 psf. Snow load = 52 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 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 = 2,500 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 9,000 lbPE = 7,500 lbQD = 0 lbQL = 3,000 lbQLr = 1,500 lbQS = 1,000 lbQR = 4,000 lbQW = 0 lbQE = 0 lbSpan:L = 11 ft Member size:4 x 6 Stress grade and species:No. 1 Douglas Fir-Larch Unbraced length:lu = L/2 = 5.5 ft Moisture content:MC < 19 percent 

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.

Determine the bending Fbx+ reference design value for 26F-1.9E softwood glulams.

A dead load of 8.8 psf acts on a roof with a 2/12 inch/inch pitch. Determine the equivalent flat-roof load.

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 36-in. o.c. Roof dead load = 8 psf. Snow load = 100 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?

Find the reduced roof live load for a one-story building which has columns evenly spaced every 15 feet in the north-south direction and 12 feet in the east-west direction. The building has an ordinary pitched roof with a slope of 8 inch/foot.

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.
