Determine the external wind pressure on the roof of the rigid-gabled frame of a building for an essential disaster operation center shown in Fig. P2.14. The building is located in Kansas City, Missouri, where the terrain is representative of exposure C and the basic wind speed for risk category IV buildings is 120 mph. Assume the wind direction is normal to the ridge, as shown in the figure. Use Kd 50.85 for main wind-force resisting systems, and Ke =1
