Determine the bending reference design value for No. 1 visually graded Douglas Fir-Larch dimension lumber.

Determine the tension parallel to grain reference design value for 2 in. wide No. 1 visually graded Southern Pine dimension lumber.

A cardboard box that has been glued to the ground experiences pressures p1 = 0.25 psi and p2 = 1.10 psi on one side. The box has dimensions L1 = 16 in., L2 = 8 in., and h = 12 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).

What is the wet service factor, CM, for the shear strength of visually graded Southern Pine 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 enclosed building. The mean roof height is 15 ft, and the roof angle is 5 degrees. The basic wind speed provided by the local building authority is 125 mph. Assume that exposure category B is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure, qh.

What is the size factor, CF, for the bending strength of No. 1 visually graded dimension lumber, except Southern Pine, that is 12 in. wide and 2 in. thick?

What is the format conversion factor, KF, for the compression strength parallel to grain of a member?

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 a partially-enclosed building. The mean roof height is 20 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 130 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 4 using the positive value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

Girders G1, G2 and G3 in the roof framing plan support loads from purlin P1. Use ASD to determine the maximum bending moment in girder G1. The roof dead load is D = 13 psf.    The reduced roof live load for this girder is Lr = 13 psf.
