Shear Rails

Developed to mitigate the impact of punching shear at slab-column connections, VSL shear rails consist of large head steel studs welded to flat steel rails. When used at column and slab connections, shear rails increase the shear capacity of the slab. Designed in accordance with current codes, the rails provide designers and contractors with a solution for slabs that is more economical and efficient than stirrups, structural steel elements or column capitals.

In addition to being quick and easy to install, VSL shear rails create less congestion. This feature makes them a great alternative to hairpins for anchorage zone reinforcement. Eliminated column capitals reduce formwork costs and provide for more efficient construction. Further, VSL shear rails may enable the use of smaller columns which reduce building mass.

Barrier Cable Systems

VSL supplies and installs complete barrier cable systems. Able to be used for all vehicle and pedestrian barrier needs and compliant with all International Building Code standards, barrier cable systems provide important advantages. One factor is economic efficiency. Because of the high strength-to-weight ratio of the strands, the cables cost less to place than precast panels, traditional cast-in-place or concrete masonry barriers. Aesthetics are another factor. Barrier cables are a visually appealing alternative to traditional systems, such as concrete walls, which can create blind spots or similar hazards.

VSL supplies and installs galvanized 1/2”, 7-wire steel strands – available with an optional plastic coating to enhance appearance and durability. Complete packages can include installation and design of strand, external anchoring devices, plates, cables, wedge sets and stressing equipment.

Unbonded Monostrand Systems

Adaptable to a variety of structures, unbonded monostrand can be easily, rapidly and economically installed. Applications for monostrand systems include elevated slabs, slab-on-grade, beams and transfer girders, joists, shear walls and mat foundations.

VSL’s monostrand systems use 0.5” and 0.6” diameter strands coated with a layer of specially formulated grease with an outer layer of seamless plastic extruded in one continuous operation to provide protection against corrosion. Each tendon is precisely coiled, cut, labeled, color-coded and delivered to the construction site. A wide variety of anchorage systems are available to meet design specifications.

Encapsulated unbonded monostrand systems are used in areas that are subject to corrosive conditions. Strands are protected at the anchorages using greased plastic sleeves and grease-filled end caps. Additionally, anchorage components are fully encapsulated in a high density polyethylene plastic covering and an optional encapsulated intermediate coupler anchorage system can be used to protect the strand at construction joints.

ÕBonded Multistrand Beam ÕBonded Slab on Grade ÕBonded Multistrand Transfer Girder

Bonded Multistrand Systems

Extensively used in bridge and transportation structures, bonded multistrand systems have been successfully applied to commercial building construction. A single multistrand tendon can hold up to fifty-five 0.5” or 0.6” strands encased in PT-Plus™ plastic or steel duct and is fully bonded using a high-performance grout.

PT-Plus™ is a corrugated duct and plastic coupler system that greatly enhances corrosion protection. Positive sealed mechanical connections between duct sections and between ducts and anchorages facilitate installation and increase durability.

When bonded multistrand systems are used for large structural members such as beams and transfer girders, design advantages include increased span lengths and load-carrying capacity and reduced deflection. Additionally, because the strands are stressed simultaneously, less labor is required and cost savings are realized.

VSLAB+® Bonded Slab Systems

VSL’s VSLAB+® Bonded Slab System consists of fully encapsulated, bonded multistrand (two to five strands) tendons contained in flat plastic ducts filled with a high-performance cementitious grout that bonds the strands to the surrounding concrete. Intermediate anchorages provide continuous encapsulation at construction joints. Tendons are protected by both PT-Plus™ plastic duct and grout.

These bonded multistrand systems have been successfully applied to commercial building, healthcare and parking garage construction by VSL. Benefits include enhanced crack and deflection control and a reduction in reinforcing steel. VSLAB+ allows for thin slab design—reducing overall building height which lowers costs for foundation, frame and facade/cladding components. Because bonded tendons may be cut with only localized loss of capacity, another significant advantage of VSLAB+ is the ease of future building modifications. Design advantages include increased span lengths and load-carrying capacities.

Additionally, the reduction of mild reinforcing steel minimizes the primary sources of corrosion and significantly reduces life cycle maintenance costs.

ÕSteel Reinforced Polymer (SRP) Composites ÕColumn Strengthening with FRP Composites ÕExternal Monostrand Post-Tensioning

Strengthening with Composite Systems

VSL sheet, rod and plate composites are designed for upgrading the load-carrying capacities of concrete, masonry and timber elements. Additionally, the V-Wrap® Carbon and E-Glass FRP systems can be protected to provide ASTM E-84/E-119 Fire Ratings. Hardwire® is another family of composite reinforcements made from ultra-high strength twisted steel wires woven into a durable fabric. When encapsulated in resin, Hardwire® forms a high strength reinforcing laminate for structural upgrades of beams and elevated slabs, as well as blast and ballistic upgrades of structures. Hardwire®, as well as the V-Wrap® Carbon and E-Glass FRP systems are lightweight, durable, non-corrosive and compatible with architectural finishes.

For structures requiring structural modifications due to load capacity upgrade, change of use, slab openings, deterioration or construction defects, VSL strengthening systems provide innovative and cost-efficient solutions.

Enlargement and Conventional Methods

Section enlargement and overlay systems are additional solutions available to increase the load-carrying section properties of structural members. VSL engineers carefully design and detail solutions to provide flexural, axial and shear upgrades using reinforced concrete and steel systems that are compatible with the existing structures.

Repair and Strengthening

Strengthening with Post-Tensioning

Strengthening designs may consist of standard or custom VSL multistrand, monostrand and VStrand™ tendons and anchorage assemblies. VSL’s full range of internal and external post-tensioning systems are suited for flexural, shear and axial strengthening applications in concrete, steel and composite structures. Applied externally or internally, VSL post-tensioning systems help control deflection, are corrosion and fire resistant and reduce concrete mass and building costs.

Post-Tensioned Structure Modification

For structural repairs made necessary by construction errors, slab openings, exposed or cut tendons or environmental issues, VSL is a one source solution. Engineering, manufacturing and installation services can be quickly mobilized into creative, efficient and cost-effective solutions. Post-tensioning repairs may involve special techniques to restore force in the tendons by placing new anchorages and stressing the tendons. Or, as required, replace corroded or fire-damaged tendons. Additionally, VSL can conduct a structural evaluation and work with the owner’s engineers to provide increased load-bearing capacity.

A systematic approach to the design and execution of these projects allows integration of engineering, manufacturing and installation capabilities into a creative, efficient, and cost-effective solution.
