Punching Shear Resistor studs are welded reinforcement components designed to improve punching shear resistance in reinforced concrete slabs. Installed around columns and concentrated load areas, they help distribute shear forces and reinforce critical slab sections.
Commonly used in flat slabs, foundations, parking structures, and other reinforced concrete applications, PSR stud rails provide additional shear reinforcement where higher load concentrations occur.

Punching Shear Resistor studs are welded reinforcement components designed to improve punching shear resistance in reinforced concrete slabs. Installed around columns and concentrated load areas, they help distribute shear forces and reinforce critical slab sections.
Commonly used in flat slabs, foundations, parking structures, and other reinforced concrete applications, PSR stud rails provide additional shear reinforcement where higher load concentrations occur.
Designed specifically for localized shear reinforcement, Punching Shear Resistor Studs are incorporated into concrete structures where elevated shear stresses develop around columns, supports, and heavily loaded areas.
These components are positioned in critical regions where concentrated forces create elevated shear demands within the concrete slab. Their placement supplements the slab's ability to resist punching shear forces around support locations.
Punching shear failures typically initiate around column perimeters where load concentrations are highest. PSR stud rails provide additional reinforcement in these zones to assist with load distribution through the slab section.
Structures subjected to high point loads often require additional shear reinforcement beyond conventional reinforcing steel layouts. These components help address localized stress concentrations induced by concentrated loading.
The components are installed using the ARC stud-welding process, forming a welded attachment to the supporting steel assembly. This installation method allows accurate positioning and repeatable reinforcement layouts.
Punching Shear Resistor studs function as part of the overall reinforcement system within the concrete structure. Their design allows them to work in conjunction with conventional reinforcing bars and structural support elements.
Suitable for a variety of reinforced concrete systems, these components are frequently utilized in commercial buildings, parking decks, transfer slabs, industrial facilities, and other structures where punching shear resistance is a design consideration.
