Dear Sir or Madam
I was wondering if you could help me or forward this email onto a person that could.
Regarding to AISC 341, Clause D2.2(4) instructs that,
‘All bolts shall be installed as pre tensioned high-strength bolts. Faying surfaces shall satisfy the requirements for slip-critical connections in accordance with Specification Section J3.8 with a fry surface with a Class A slip coefficient or higher’.
This is a problem for one of our clients. We do not have sufficient knowledge of the background research or case studies to decipher why the code specifies the use of HSFG bolts and therefore can’t speculate as to what happens if we are non-code compliant.
Is it possible for you to refer me to relevant case studies/ background research on the reasoning behind Clause D2.2(4) for us to speculate as to what will happen if effectively we don’t preload the bolts.
Regards,
