Determine the external wind pressure on the roof of the rigid-gabled frame of a school building shown in Fig. P2.13. The structure is located in a suburb of Chicago, Illinois, where the terrain is representative of exposure B, and the basic wind speed for risk category III buildings is 54 m/s. Assume the wind direction is normal to the ridge as shown.
