A beam has dimensions of b = 14 in., h = 28 in., and d = 25.5 in. and is reinforced with 5 No. 8 bars. The concrete strength is 7,300 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 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 5 degrees. The basic wind speed provided by the local building authority is 135 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.
