PSR Studs (Punching Shear Resistor)

Punching shear resistor (PSR) studs are large headed shear connectors that are welded to flat steel bars (creating stud rails).

Used for shear reinforcement in flat concrete slabs to replace stirrups and column capitals to resist the punching shear stress in the slabs.

Description

PSR Studs (Punching Shear Resistor)

PSR Studs (Punching Shear Resistor) are large headed shear connectors that are welded to flat steel bars (creating stud rails). Used for shear reinforcement in flat concrete slabs to replace stirrups and column capitals to resist the punching shear stress in the slabs.

Predetermined length and diameter, according to design specifications in compliance with IBC and UBC Structural Steel Welding Standards. Used to extend the column perimeter into the floor or foundation slab. This reduces the amount of reinforcing bar required in an area and column congestion resulting in easier and faster installation, as well as lower cost.

Using these punching shear resistor stud rails, you increase the punching shear capacity at the base of the concrete columns, resulting in a significant reduction in slab thickness. This creates a substantial savings in labor and material costs.

Benefits of Using PSR Stud Rails:

  • Eliminating the need for column capitals and stirrups
  • Reduction of setup and installation time.
  • Reduction of congestion around column/slab connections.
  • Distribution of force over a greater critical area.
  • Providing higher tensile strength and more ductile performance of the concrete slab.

*Other sizes available upon request.

Please Note

  • Weld studs listed in the table above are the Standard Minimum Length
  • Punching Shear Resistor Studs can be requested in any required length above the minimum
  • Listed ferrule is for standard flat down hand position
  • Stud Welding Products can provide the studs, equipment, and fabricate the stud rails (assembled)
