Zone 3:
Zone 3 Overhang:
Step 2: Wall sheathing suction loads pressure coefficient
Pressure coefficient equations developed from C&C, Figure 30.4 graphs of ASCE 7-10 coefficients:
Zone 4:
Zone 5:
Step 3: For all zones – internal pressure coefficient
GC pi = +/-0.18
Step 4: Calculate roof sheathing and wall sheathing suction pressures for all zones using
Equation 8.14
Zone 1:
Zone 2:
Zone 2 Overhang:
Zone 3:
Zone 3 Overhang:
Zone 4:
Zone 5:
Note: This solution matches the information in Table 8-8.
