Punching shear is a type of failure in structural elements like slabs or foundations, typically occurring around columns or concentrated loads. It happens when a high localized force causes the slab to shear around the perimeter of the column, almost like a “punch” through the slap - hence the name. 

Punching Shear Failure can occur without adequate reinforcement. 

Stud Rails are your solution! 

Stud rails are vertical steel studs welded to horizontal rails, placed around the column inside the slab.  They act as shear reinforcement, increasing the slab’s capacity to resist punching shear by transferring the loads deeper into the slab.  This reinforcement changes the failure mode from brittle punching to a more ductile behavior, improving safety. 

At Jobsite Stud Welding we use studs of a predetermined length and diameter, according to your design specifications in compliance with IBC and UBC Structural Steel Welding Standards, these studs are welded onto rails and used to extend the column perimeter into the floor or foundation slab. This reduces the amount of reinforcing bars required in an area and column congestion, resulting in easier and faster installation, as well as lower costs.
