Given: The plan and section of the building in Fig. 3.B. The basic wind speed is 100 mph, and Exposure B applies. The building is enclosed and has a standard occupancy classification. Roof dead load D 15 psf on a horizontal plane. Wind forces to the primary LFRS are to be in accordance with ASCE 7.

Fig. 3.B

Find:

a. The wind force on the roof diaphragm in the transverse direction. Draw the loading diagram.

b. The wind force distribution on the roof diaphragm in the longitudinal direction. Draw the loading diagram.

c. The total diaphragm shear and the unit diaphragm shear at line 1

d. The total diaphragm shear and the unit diaphragm shear at line 4
