Pile cap edge
Pile cap edge
(OP)
Hi all. I was wondering why most of the pile cap design adopt a pile face to edge of pile cap distance of 150mm? i assume that if concrete cover is 75mm (3") and ties diameter is 16mm (5/8") and rebar diameter of 32mm (5/4") = 123mm or 125mm (5") that is a conservative estimate of the pile face to edge of pile cap distance. because we can still reduce 75mm concrete cover by use of formworks, and using a smaller rebar diameter.
but why adopt 150mm?

RE: Pile cap edge
Also, in thinner pile caps, you should be checking corner pile's punching shear capacity, although it rarely controls for normal pile caps.
One other thing is that the piles are more than frequently allowed to be installed with lower tolerance levels. I remember 3" being an acceptable number.

It also allows some tolerance, driven piles will have a 2-3" driving tolerance and unless the installed pile is outside this tolerance, the reinforcement scheduler will not allow for minor dimension changes following pile installation.
