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 = 14 psf.    The reduced roof live load for this girder is Lr = 12 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 25 ft, and the roof angle is 20 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 MWFRS design wind pressure, p, on Zone 4E for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.
