Abstract:The rapid development of prefabricated steel structure in China has made a higher requirement to the connection property and economic performance of high-strength bolts. Through a large number of searches of relevant scholars at home and abroad, the factors affecting the shear connection performance of friction style high-strength bolts were summarized, and the research status of these factors was classified and reviewed. Based on the comparison of relevant codes in China, Europe, the United States and Australia, the calculation formulas of shear bearing capacity of friction style high-strength bolts were compared and analyzed. The design values of shear connection capacity of 8-8 grade friction style high-strength bolts were calculated. The sliding coefficient of friction surface and the pre-tension force of high-strength bolts were compared. Finally, the shortcomings of the current research on shear connection performance of friction style high-strength bolts were pointed out, and suggestions on the content and direction of future research were put forward.

Keywords:friction style high-strength bolt; shear capacity; influence factor
