PSR studs are large-headed shear connectors that are welded to flat steel bars (creating stud rails) and used for shear reinforcement in flat concrete slabs to replace stirrups and column capitals to resist the punching shear stress in the slabs.
Using these PSR stud rails, increases 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. PSR Studs have heat codes stamped on the head that allow traceability to the specific Mill Certification of the stud. PSR studs are available in any length over the standard minimum.
