>>From the examples it looks like you use a critical section that is located at distance of "d/2" when

>>checking the individual pile one-way shears, but use a distance of "d" when checking the column one-

>>way shear. Why are you using the different distances? I would have thought you would just use "d" for

>>both the pile and column one-way shear check.

From the first impression it seems we shall use d for one-way shear check, for both corner  pile and

column case.

I highlighted corner pile in red and the answer is the in the corner  word.

 Column one way shear check refers to CSA A23.3-04 13.3.6.1 which uses d

 Corner one way shear check refers to CSA A23.3-04 13.3.6.2 which uses d /2

I check through ACI 318-11 and find there is on specific one-way shear definition similar to CSA A23.3-

04.

 ACI 318-11 quotes corner column in clause 11.11.1.1, which used d/2. The one-way shear check in ACI

318-11 is same as beam shear check, which shall refers to clause 11.2.1.1, in this beam shear case, d

shall be used.

From above comparison, the use of d/2 for corner pile one-way shear check and use of d for column

one-way shear check in my spreadsheet is correct !
