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?

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

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

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.

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 = 2,500 lbPL = 1,000 lbPLr = 1,500 lbPS = 2,000 lbPR = 500 lbPW = 0 lbPE = 0 lbLength:L = 11 ftMember size:4 x 8Stress grade and species:No. 1 & Better Douglas Fir-LarchUnbraced length:lu = L = 11 ftMoisture content:MC < 19 percent

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.

The density of a dried piece of 2×6 Aspen dimension lumber that is 20 feet long and has a moisture content of 9% is _______.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 11.03 psf acts on the tributary area of one of the columns, determine the equivalent point load that acts on the column.

Determine the flat roof snow load, pf, for a building kept just above freezing with a roof that is sheltered in terrain category D and has a risk category of II. Assume the ground snow load is 54 psf. Do not consider the minimum roof snow load, pm.
