1 Introduction
As a commonly used fastener, bolts are widely used in various structural connections. As a new type of bolt connection method, torsion-shear high-strength bolts have high strength, good seismic resistance and reliable connection effects, so they have been widely used and researched in the engineering field. This article will introduce in detail the structure, performance and application fields of torsion-shear high-strength bolts, and analyze its future development direction.
2. Structure and working principle of torsion-shear type high-strength bolts
Torsional shear high-strength bolts consist of a bolt body and a nut, and their structure is similar to traditional bolts. However, torsion-shear type high-strength bolts are equipped with multiple torsion-shear parts on the bolt body, so that they can absorb and disperse the load through torsional shear deformation when stressed. This structural design makes the torsion-shear type high-strength bolts have higher shear strength and torsion capacity.

Torsional shear high-strength bolts are made of high-strength materials and have high tensile strength and shear strength. Its strength level is usually higher than ordinary bolts and can meet the demand for high-strength connections in engineering structures.
3.2 Seismic performance
Because torsion-shear type high-strength bolts use torsion-shear deformation to absorb and disperse loads, they have better seismic performance under the action of external forces such as earthquakes. Research shows that torsion-shear type high-strength bolts can effectively reduce the stress concentration of the structure and improve the overall seismic resistance of the structure.
