Volume II DETERMINING SITE-SPECIFIC LOADS 8
EXAMPLE 8.10. LOAD COMBINATION EXAMPLE PROBLEM
Given:
Use the flood loads from Example 8.3:
• F sta = 0
• F dyn = 909 lb
• F brkp = 625 lb
• F i = 2,440 lb
• d s = 4.6 ft
Use for wind loads:
• Roof span = 28 ft
• Roof pitch = 7:12
• Wall height = 10 ft
• Wind uplift load = 33,913 lb (pre-factored with 0.6)
• Exposure Category D (multiply Exposure C wind loads by 1.18 at 33 ft mean roof height)
• 1.18 is a conservative value because while the higher Exposure Category D has been
factored, the lower roof height (24 ft versus 33 ft) has not. Refer to ASCE 7-10,
Figure 28.6-1 for guidance.
