Shear Strength of Pile Shaft (Constant)

Determination of a constant shear strength at the pile shaft from the total resistance using an equivalent pile diameter and a bond length.

τmax=Fr,sdeq×π×lb

Fr,s

Total resistance of the pile shaft (friction)

deq

Equivalent pile diameter (circular surface)

lb

Bond length of the pile
