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

All of the following species of trees may be included in the “Hem-Fir” Species Combination except _______.

Use the Simplified Alternative Procedure in ASCE 7-10 Chapter 12, Section 12.14 to answer this question. Assume that the building meets the limitations described therein. A two-story building with the following characteristics has a bearing wall system consisting of light-frame (cold-formed steel) walls sheathed with wood structural panels rated for shear resistance. A certain shear wall in the building is 100 feet long by 22 feet tall and weighs 15 psf. Determine the seismic base shear, V, for the wall.Risk Category ISite Class DSS = 0.25, S1 = 0.10

What is the temperature factor, Ct, for the tensile strength of sawn lumber that has a constant temperature of 140°F?

Determine the maximum bending moment in the following beam. Assume normal temperatures, bending about the strong axis, and no incising. Ignore the weight of the beam.Load:PD = 520 lbPLr = 2,080 lbLoad combination:D + LrSpan:L = 9 ftMember size:4 x 12Stress grade and species:No. 1 & Better Douglas Fir-LarchUnbraced length:lu = 0Moisture content:MC < 19 percentLive load deflection limit:Allow.

Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing an enclosed building. The mean roof height is 25 ft, and the roof angle is 5 degrees. The basic wind speed provided by the local building authority is 115 mph. Assume that exposure category D is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure exposure coefficient, Kh.
