ABSTRACT
The load-bearing capacity of high-strength bolts with single-side tapping shear connection was experimentally studied. The ultimate shear capacity of a single bolt in the friction stage and the ultimate shear capacity in the pressure stage were measured. The test results show that when the tapping high-strength bolt connection is designed according to the pressure type high-strength bolt, the average value of the ultimate shear capacity of the bolt measured by the test has a larger safety reserve than the calculated ultimate shear capacity of the bolt, which can meet the design requirements of the pressure type high-strength bolt. However, when it is designed according to the friction type high-strength bolt, the average value of the shear bearing capacity of the bolt obtained by the test is less than that calculated by the standard, and the relative slip between plates obtained by the test is relatively large, which cannot meet the normal use limit state requirements of the friction type high-strength bolt in shear.
