Procedure for slip-critical connection preparation

[Heldbaum]

Hi everyone, is there anyone who can list in a few points the procedure a steel contractor should follow to get a proper slip-critical connection, including proper bolt tightening and all inspections..? I understand when slip-critical connections shall be specified, Code of Standard Practice is clear on that and I understand the difference between sc and bearing type, that plates shall be clean of paint etc. it is just not enough - I have a steel contractor who I work with, I do engineering and shop drawings for him, and he's never done slip critical connections and I do not have enough knowledge to explain him step by step what needs to be done to get a slip critical connection from fabrication point of view and what shall be inspected and when prior to steel assembly. I'd appreciate your help.

Top priority is proper preparation of contact surfaces.

See "When-And When Not-To Specify Slip-Critical Connections" in the January 2016 issue of "Modern Steel Construction" magazine. The article includes a summary of the necessary steps.
