求助。
高强螺栓施工,用转角法拧紧时,初拧达到‘密贴’状态后,再加拧一个角度,完成终拧。有谁能指教,初拧的轴力为多少才合适?有没有这方面的规定,或者论述?
Hi! Everybody, who can kindly help with the solution about how to determine the initial pre-tesion force corresponding to 'snug tight' state when turn-of the-nut method is applied for tightening high strength bolt? I read of some descriptions on 'snug tight' from AISC web, and some project specifications, but never quantified requirement.  
Thanks in advance.
