The choice of composite types of building options over more traditional types of construction methods and materials makes it essential to consider all aspects of the construction process. This means not only selecting the correct size of steel beams and then the correct concrete slabs for the job, but also selecting the ideal shear studs based on the specifics of the building or project.
Also known as shear connectors, the purpose of these drawn arc weld studs is to connect and hold the concrete slabs and the steel beams together, creating a composite structure. The overall strength of the combination of materials is stronger than either material rated separately, which makes this an ideal match for high rise buildings, warehouses, industrial facilities, bridge decks, elevated walkways and any other similar type of structure or building.
What To Consider
In structural applications, including for buildings as well as for bridges and decks, there are specific code requirements for the choice of shear studs. This also clearly provides the pattern and spacing the shear connectors are to be placed.
The speed of the process of attaching the weld studs is incredibly fast, typically only a second per weld stud, even with an operator with limited experience. As it is a set process that is determined by the diameter of the fastener, the type of material and the welding current used, each weld stud is identical in placement and in the quality of the weld.
The choice of shear studs is instrumental in preventing lifting or separation of the concrete slab and steel beam. With a solid connection created by the shear connectors, the two materials cannot move independently. This eliminates the risk of twisting, buckling or sagging, even over long spans of unsupported deck as found on bridges or building decks.
