Metal Shear Connector – The Backbone of Structural Steel Construction
As the demand for high-rise buildings and large industrial facilities increases, stronger and more efficient construction materials and techniques are needed. Structural steel is one popular choice because it provides greater strength and stability than traditional building materials. However, to ensure the structural integrity of steel construction, a reliable connector is required. This is where the metal shear connector steps in.
The metal shear connector is a specialized component used to connect steel beams and concrete slabs in composite construction. The connector is designed to transfer horizontal forces between steel beams and concrete slabs, which can be challenging due to their different elastic moduli. When concrete is placed on top of a steel beam, the two materials behave differently under load. Concrete resists compression while steel resists tension. The metal shear connector provides a bond between the two materials, making them act as a single unit.
There are several types of metal shear connectors available, but the most common ones are headed studs and connectors with welded studs. Headed studs are short cylindrical rods with a fixed head on one end, which is embedded in concrete. Meanwhile, connectors with welded studs have studs welded onto a plate, which can be embedded in concrete. Both types of connectors have a shank that passes through the steel beam, creating a secure connection between the steel and concrete elements.
The metal shear connector is critical because it enhances the load-carrying capacity of composite construction, allowing for greater efficiency and cost-effectiveness. Additionally, it enhances the stiffness of the composite structure, reduces deflections, and increases the resistance to seismic and wind loads.
In November 2019, news broke out about a 70-story tower in Oakland, California, that was constructed with a metal shear connector manufactured by a Chinese company called Jiaxing Jinyi. The tower was reported to have used more than 3,000 metal shear connectors in its construction. This news showcases the importance of metal shear connectors in structural steel construction and how its quality and reliability play a vital role in the safety and integrity of buildings.
In conclusion, the metal shear connector may seem like a small component, but it is, in fact, the backbone of composite construction. It is responsible for connecting steel beams and concrete slabs, enhancing the load-carrying capacity, stiffness, and resistance of composite structures. The use of high-quality and reliable metal shear connectors is essential to ensure the safety and integrity of buildings of all types and sizes.
We are engaged in the design, research and development, production, and sales of fiber reinforced composite (FRP) connectors for prefabricated buildings, stainless steel insulation connectors, and structural insulation integrated anchors.
