Study on the Working Performance of Friction-Typed High-Strength Bolt Connectors in Sliding Stage

Slip load is an important parameter to test the anti-slip coefficient.It may not be accurate due to false appearance in accordance to the criterion of high-strength bolt connectors.Working performance of anti-slip connectors in sliding stage was studied by self-designed checking device in this paper.The results show that pointer return could not reflect the whole slipping performance for pointer return is preceded by slip.Therefore,it is more reasonable judging the slip load by connectors slid.
