For glulams, what moisture content value is considered a dry condition?

What is the moment of inertia, Ixx, about the X-X axis for 3-1/2 in. x 12 in. Western Species glulams?

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 = 1,000 lbPL = 2,500 lbPLr = 3,500 lbPS = 2,000 lbPR = 5,000 lbPW = 2,000 lbPE = 0 lbLength:L = 14 ftMember size:4 x 12Stress grade and species:No. 2 Douglas Fir-LarchUnbraced length:lu = L = 14 ftMoisture 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 floor system is 24-in. o.c. Floor dead load = 17 psf. Floor live load = 145 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?

Checking the adequacy of a member of known size is considered _______.

A pin-connected wood truss is loaded and supported as shown. Determine the axial force produced in member GH if PB = 700 lb, PC = 2,100 lb, PD = 3,200 lb, L = 6 ft, and h = 8 ft. Positive choices indicate tension. Negative choices indicate compression.

The density of a dried piece of 4×10 Hem-Fir dimension lumber that is 12 feet long and has a moisture content of 13% is _______.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 12.82 psf acts on the tributary area of one of the 50-ft girders, determine the equivalent distributed load that acts on the girder.

The two columns in the following floor framing plan support only loads from a bowling alley on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.7 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.

A wood member is loaded as shown. Using ASD, determine the adjusted bending strength, Fb’. Assume normal temperatures, no incising, and that all loads act in the directions shown. Ignore the weight of the member.Load:PD = 1,000 lbPL = 0 lbPLr = 0 lbPS = 0 lbPR = 0 lbPW = 7,500 lbPE = 5,000 lbQD = 1,500 lbQL = 3,500 lbQLr = 4,500 lbQS = 500 lbQR = 1,000 lbQW = 0 lbQE = 0 lbSpan:L = 12 ft Member size:4 x 6 Stress grade and species:Select Structural Douglas Fir-Larch Unbraced length:lu = 0 ft Moisture content:MC > 19 percent
