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 = 12 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 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 120 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 exposure coefficient, Kh.

A cardboard box that has been glued to the ground experiences pressures p1 = 0.70 psi and p2 = 1.05 psi on one side. The box has dimensions L1 = 18 in., L2 = 8 in., and h = 13 in. Use the pressure tributary to the diaphragm (lid) of the box to determine the reaction force V2 between the diaphragm and the shearwall (short side of the box).

A beam has dimensions of b = 18 in., h = 22 in., and d = 19.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 7,900 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the depth to the neutral axis, c.

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 IISite Class DSS = 0.75, S1 = 0.30

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 20 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 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.

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 G3. The roof dead load is D = 11 psf.    The reduced roof live load for this girder is Lr = 20 psf.
