Headed cast in place anchor spacing
I see that in the program, the anchor minimum anchor spacing is limited to 6da. I assume this is per chart ACI 17.9.2(a) Torqued. Is there a provision for using 4da for not torqued. I could not find the definition of not-torqued. The bolts are tightened using the turn of nut method per ASCE Design Guide 1.

Hi Aaron,
To help determine whether a cast-in-place anchor requires a torque or not, looking in the specific anchor's instructions for use can help clarify as a torque may be listed. Ultimately, if the specific anchor manufacturer does not publish a minimum anchor spacing, then determination of which anchor spacing to use per ACI is up to the engineer of record.
