Grout sequence? Grout sequence? ckirkland (Industrial) (OP) 25 Jun 16 14:47 Hey guys, first time poster. Question is per AISC, must erector fully tension (snap) all TC bolts prior to grouting the columns? Owner spec is undefined on the subject. more info A325 bolts single story not slip critical RE: Grout sequence? wannabeSE (Civil/Environmental) 25 Jun 16 18:16 I would say no, they do not need to be pretensioned prior to grouting. The columns need to be plumb and beams level. See section 7.7 of AISC 303 Code of Standard Practice for Structural Steel Buildings and Bridges https://www.aisc.org/content.aspx?id=2884#code RE: Grout sequence? JAE (Structural) 25 Jun 16 18:44 You're not talking about the anchor rods at the column base plates, correct? You are referring to all the framing connections up above?
