Figure 7 -11: GROUP ® Results

From Figure 7-11, the important thing to look for is that the axial capacity of the pile (from the T-Z curve) is greater than or equal to 2 times the axial reactions (for an axial FS of 2.0). In this case the 85 kips from the T-Z curve is greater than 40*2= 80 kips. Since the T-Z curve was changed during design, the Helicap® run needs to be run again to get an 85 kip pile. Here are the results.
