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 G2. The roof dead load is D = 15 psf.    The reduced roof live load for this girder is Lr = 15 psf.

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 15 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 150 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure, qh.

What is the section modulus, Sxx, about the X-X axis for 2 x 8 dimension lumber?

For sawn lumber, the time effect factor would be used to determine which of the following adjusted design values? Select all that apply.

What is the load duration factor, CD, for a load duration of one week?

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 20 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 velocity pressure exposure coefficient, Kh.

What is the incising factor, Ci, for the shear strength of a sawn-lumber 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 an enclosed 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 140 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 3 using the positive value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

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 special reinforced concrete shear walls. A certain shear wall in the building is 120 feet long by 24 feet tall and weighs 100 psf. Determine the seismic base shear, V, for the wall.Risk Category ISite Class CSS = 0.75, S1 = 0.30

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 80 feet long by 18 feet tall and weighs 15 psf. Determine the seismic base shear, V, for the wall.Risk Category ISite Class ASS = 0.50, S1 = 0.20
