8 DETERMINING SITE-SPECIFIC LOADS Volume II
EXAMPLE 8.8. LATERAL CONNECTION FRAMING LOADS FROM WIND
Given:
• Wind load is based on 150 mph, Exposure C at 33-ft mean roof height, and wall and
diaphragm framing as shown in Illustration A
• Building is enclosed
• Wall height is 10 ft
• Stud spacing is 16 in. o.c.
• Sheathing effective area is 10 ft 2
• ASD velocity pressure q = 29.38 psf (from Example 8.5)
• Wall suction equations for Zone 4 and Zone 5 are provided in Example 8.7
• Internal pressure coefficient for wall sheathing is GC pi = +/- 0.18
