>>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 !
