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 5 degrees. The basic wind speed provided by the local building authority is 115 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.

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 building frame system consisting of steel and concrete composite special shear walls. A certain shear wall in the building is 80 feet long by 20 feet tall and weighs 80 psf. Determine the seismic base shear, V, for the wall.Risk Category IISite Class ASS = 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 120 mph. Assume that exposure category C 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 using the negative value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

A cardboard box that has been glued to the ground experiences pressures p1 = 0.80 psi and p2 = 1.20 psi on one side. The box has dimensions L1 = 19 in., L2 = 9 in., and h = 14 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).
