Point of Fixity in Drilled Shafts
Point of Fixity in Drilled Shafts
(OP)
I am doing an analysis of drilled shafts supporting a bridge pier using the L-Pile program. This program allows me to input loads and soil layers, and gives me output such as pile head deflection, maximum moment, maximum shear, etc. It also gives graphs of deflection v. depth, bending moment v. depth, shear v. depth, and soil reaction v. depth. My question is: Where is the point of fixity? Is there a definite answer or is there a guideline somewhere?

deflection leads to a conservative design. In case of pile design
for jetties etc, where the pile extends fairly high above the soil,
the K.L/r factor becomes unduly large if you consider point of
zero deflection. We have used point of maximum bending
moment as the point of fixity for this purpose.
