I understand that longitudinal bars but be within 6" of a corner of a tie. However, is there a limitation on the maximum allowed spacing of the longitudinal bars, regardless of corners? I had always thought it was 12", but I can't find the reference for this.
Example, 10" x 20" col. I want to use 4 bars and As(min)=0.01Ag = 2.0si. I choose 4 #7 = As=2.4si. Can I put the 4 bars in the corners with 1 tie? Along the long side of the col, the bars will be about 14". Each bar will be at a corner, which is good, but what about a max spacing requirement?
