A cardboard box that has been glued to the ground experiences pressures p1 = 0.20 psi and p2 = 1.00 psi on one side. The box has dimensions L1 = 15 in., L2 = 7 in., and h = 11 in. Use the pressure tributary to the diaphragm (lid) of the box to determine the reaction force V1 between the diaphragm and the shearwall (short side of the box).

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 open building. The mean roof height is 15 ft, and the roof angle is 30 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 MWFRS design wind pressure, p, on Zone 4E for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

Determine the ASD adjusted design shear strength, Fv’, for the following beam. Assume normal temperatures, bending about the strong axis, and no incising. Ignore the weight of the beam.Load:wD = 300 lb/ftwLr = 420 lb/ftLoad combination:D + LrSpan:L = 10 ftMember size:4 x 8Stress grade and species:No. 1 & Better Douglas Fir-LarchUnbraced length:lu = 0Moisture content:MC > 19 percentLive load deflection limit:Allow. Δ ≤ L/360

What is the section modulus, Sxx, about the X-X axis for 2 x 10 dimension lumber?

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 open building. The mean roof height is 20 ft, and the roof angle is 20 degrees. The basic wind speed provided by the local building authority is 145 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the external pressure coefficient GCpf on Zone 4 for Load Case A.

What is the format conversion factor, KF, for the strength of a connection?

What is the resistance factor, φ, for the minimum modulus of elasticity of a member?

What is the resistance factor, φ, for the compression strength parallel to grain of a member?

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 size factor, CF, for the bending strength of No. 1 visually graded dimension lumber, except Southern Pine, that is 4 in. wide and 2 in. thick?
