Axial-load Capacity of single pile

Posted in Piles Engineering | Email This Post Email This Post

Pile capacity Qu is the sum of the shaft and toe resistances, Qsu and Qbu, respectively.

The allowable load Qa is determined by:

Qa=(Qsu)/F1 +(Qbu)/F2

where
F, F1, and F2 are safety factors. Generally F lies between 2-3 for permanent structures but value can change depending on the perceived reliability of the analysis and construction as well as the consequences of failure.

    Can someone please detail calculation for skin friction for CAST In SITU pile in clay and In sand?please note that, in practical cases we have SPT data only.Can I use this data to calculte pile capacity in clay in sand(for cAt in situ pile ). Please note that wash boring is used to mAke the bore.
