A simply supported beam with dimensions of b = 14 in., h = 22 in., d = 19.5 in., and L = 19 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.4 kips/ft and a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

A cardboard box that has been glued to the ground experiences pressures p1 = 0.45 psi and p2 = 1.30 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).

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 115 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, qh.
