- Abstract
For the friction-type high-strength bolted joint, the bolt fracture can cause redistribution of interface friction, which can seriously endanger the connection safety of structural members. However, current studies barely focus on the redistribution of interface friction after bolt fracture. Therefore, this paper will specifically carry out finite element analysis on the redistribution of interface friction caused by fractured bolts. Firstly, the refined finite element model of friction-type high-strength bolted joint is used to investigate the variation of interface friction under uniform temperature as well as the distribution of interface friction in different areas. Furthermore, random selection method is introduced to explain how the quantity and location of fractured bolts influence the redistribution of interface friction. Finally, the mathematical model of friction redistribution is built to describe the redistribution of interface friction in the high-strength bolted frictional steel connection after bolt fracture. After validation, the mathematical model can well describe the redistribution of interface friction caused by fractured bolts, which can provide useful reference for the frictional steel connection design of high strength bolts.
