Abstract

Abstract

Four groups of twelve high-strength bolted connection specimens with different hole types were fabricated and tested in shear using Q235 steel， Q355 steel， and Grade 10.9 high-strength bolts. A finite element model was established to analyze the shear performance of high-strength bolted connections with different hole types， investigating the effects of three factors： bolt hole type， preload loss rate， and anti-slip coefficient. The variation patterns of preload force and anti-slip coefficient for connections with various bolt hole types were identified. The results showed that changes in bolt hole type and preload force had a minor effect on the ultimate shear bearing capacity of the specimens. In contrast， the anti-slip coefficient had the greatest influence on the slip load and ultimate shear bearing capacity of standard hole specimens， and the smallest effect on the initial slip load of slotted hole specimens with internal force perpendicular to the slot direction.
