Thanks Hokie! Yes I have 4#6 and 4#8. Didn't know if there would be any reason to need a larger development length for the #8 (even though they are in excess of the original design).
Let's say column was designed with (x8) #6 bars (A_s = 226 in^2). If half the verticals were switched to #8 bar for constructability (A_s = 314 in^2), we can reduce the specified development length of all the dowels by (226/314 = 0.72)? Is this correct? Or does this reduction only apply to the...
