Shear Stud

Definition

A shear stud is a metal stud welded to the top of a beam in a composite slab-on-deck.

Purpose

The purpose of a shear stud is to enhance the composite action between a steel beam and a concrete slab, increasing the strength and stiffness of the combined structure.

Examples of Use

• In bridge construction, shear studs are used to connect steel girders to the concrete deck.
• Commercial buildings with composite floor systems utilize shear studs to bond the steel beams and concrete slabs.
• Industrial platforms and mezzanines employ shear studs to create strong, integrated floor systems.

Related Terms

• Composite Beam: A beam that combines steel and concrete to improve structural performance.
• Weld: The process of joining two materials, typically metals, by melting and fusing them together.
• Decking: The structural surface that supports flooring or roofing materials.

Notes

Shear studs are crucial in composite construction, providing the necessary shear connection to ensure the structural efficiency of composite beams.
