between the foundation members and soil in the load path.
EXAMPLE 9.6. UPLIFT LOAD PATH FOR SUPPORT BEAM TO PILE
Given:
Find:
• Refer to Figure 9-18
• Unit uplift load at top of floor beams = 463.2 plf (from Example 9.5)
• Pile spacing = 9.33 ft
• Continuous beam of 28-ft length at end wall

1. Uplift load for support beam-to-pile connections.
2. Number of bolts required for support beam-to-pile connections for wind uplift.
Solution for #1: The uplift load for the support beam-to-pile connections can be determined as
follows:
Uplift:
Tributary length of center pile connection = 9.33 ft
