Double Stud Anchor
DSA Reinforcement
Stud Rail is a double-headed stud anchor (DSA)
reinforcement system, typically used for concrete deck-to-
column connections. The system is designed to transfer
the load further into the concrete deck, create a larger
shear area around the column, and resist punching shear
forces.
Using the Stud Rail system can also eliminate the need
for forming column capitals or drop heads. This provides
signifi cant savings, since these column details are diffi cult
to form and place.
Each stud is double-headed so the load transfer is equal at
the top and bottom of the Stud Rail assembly. Each stud is
available in diff erent sizes to match the engineered loads
for each project.
The Stud Rail assembly is available with a bottom strap
or optional top wire, allowing the contractor to determine
the installation sequence. The assembly can be positioned
before or after structural reinforcement and/or post-tension
tendons are placed.

with DSA Chairs
The Stud Rail assembly is engineered for every
connection, on every fl oor, on every project. During
production, each assembly is color-coded to correspond
with the shop drawings for site installation.
This detailed planning eliminates fi eld welding and reduces
installation time, providing signifi cant labor-savings and
better shear load transfer.

Without Stud Rail, the deck-to-column
connections are prone to punching
shear failure.
With Stud Rail in place, the shear stress
is transferred to a larger area around the
column.
DSA Shear Reinforcement
Specifi cation A-1044-16 Type 2
The specifi cation covers steel stud
assemblies for shear reinforcement
in concrete. The stud assembly
consists of double-headed stud
anchors attached to a steel shape
(strap or wire). The steel shape is
suffi ciently rigid to position the studs
in the appropriate reinforcement
location, direction and spacing.
Steel Bars, Carbon and Alloy
Specifi cation A-29
The specifi cation covers steel stud
properties for shear reinforcement
in concrete. The minimum yield is
51 KSI, minimum tensile is 65 ksi,
elongation in 2” equals 20%, and
reduction area equals 50%.

Double Stud Anchor Rebar
DSAR Reinforcement
Double Stud Anchor Rebar is primarily used to increase
the punching shear resistance of cast-in-place concrete
slabs without increasing the slab’s thickness.
DSAR rails consist of double-headed ribbed studs
attached to a steel fl at bar for spacing during concrete
pour.
DSAR can be used in slab-on-grade foundations and
in elevated slabs, such as reinforced concrete slabs
or post tensioned slabs. When used in elevated slabs,
DSAR can eliminate the need for drop panels or col-
umn caps, thus reducing the costs associated with
formwork.
Designing with 60 KSI yield
DSAR reduces total number of
studs by 14%
80 KSI yield DSAR available
DSAR Stud Rail Reinforcement
Compared to traditional reinforcement
systems, DSAR has the following added
benefi ts:
Meets requirementsof ASTM 1044-16 type 2.
Meets ACI 318-19 for all slab thicknesses.
Reduces Congestion of reinforcement system.
Quick installation times leading to reduced labor cost.
Thinner slab will allow for a lower fl oor-to-fl oor height.
Improves the ductility of slabs.

DSA Plastic Chairs
On most Stud Rail projects, DSA Plastic Chairs are
necessary to maintain proper positioning and concrete
cover. Plastic chairs are available in four sizes to meet
these project dimensions and specifi cations.
When installed on the project, the DSA Plastic Chairs
are simply snapped closed over the Stud Rail strap and
fastened to the deck through the preformed holes with
nails or screws.
