Where are shear studs used?

In stud welding, shear studs are used to secure framed buildings by creating a shear connection between steel and concrete. These fasteners secure beams and resist loading between concrete and steel components in a composite construction.

They are widely used in the load-bearing structures of high-rise buildings, especially in the rigid columns with concrete wrapped around the outer layer of steel. By welding studs to increase the connection area and the shear strength of the contact surface, the steel column and the concrete surface are firmly combined and bear the force together. In addition, shear studs also play an important role in steel-concrete composite beam structures.

When designing a structure, it is generally necessary to consider whether shear studs connections are required. The following are some situations where shear bolt connections are required.

1.Connections between shear members: For example, the connection between beams and columns usually requires the use of shear studs to ensure the stability and safety of the connection.

2.Connection of structural bridges and railway tracks: These structures need to withstand shear and torque in different directions and magnitudes, so shear studs connections are required to ensure their stability.

3.Connecting thin plates or components of inhomogeneous materials: If thin plates or components of inhomogeneous materials are to be connected together, shear studs connections are often used to ensure the stability and safety of the connection.

The extensive use of shear studs ensures that steel and concrete can maintain integrity when subjected to horizontal forces, enhances the structure's earthquake resistance and wind pressure resistance, and promotes collaborative work in the structure.
