Bonded Multistrand Systems

Bonded Slab Systems

Bonded multistrand systems are extensively used in bridge and transportation structures as well as in larger concrete members, such as transfer slabs and transfer beams or girders. Benefits of bonded multistrand systems include; higher ultimate moment capacity compared to unbonded tendons, redundant anchoring of the prestressing steel through bond, further reductions in mild reinforcement, a highly alkaline corrosion protective encasement of the prestressing steel, transfer of large post-tensioning forces in a more compact manner, labor and material cost savings in large tendon applications, and minimal time to procure materials.

Featuring the same benefits as bonded multistrand posttensioning, our bonded slab systems utilize flat ducts to maximize eccentricity of the prestressing and to reinforce slabs as thin as 5". Bonded slab systems allow for future modifications, such as drilling, coring, and openings. When bonded prestressing steel is cut it behaves similar to rebar in that the loss of force is localized. These systems are used in a variety of applications, including bridge decks, parking deck slabs, transfer slabs and containment structures to enhance long-term durability.

Post-Tensioning Repair Solutions STRUCTURAL TECHNOLOGIES has an array of specialized products and systems used to repair, strengthen and protect existing post-tensioned structures. Our inventory includes product solutions for every component of a post-tensioning system – as well as specialized equipment used to install these systems in existing structures.

Stay Cable Systems

A leader in stay cable technology—STRUCTURAL TECHNOLOGIES' VSL Stay Cable System features strands that are individually protected and anchored with fixed or adjustable anchorages. By design, the system allows for an unlimited number of strands; independent strand anchoring; individual strand corrosion protection; and individual strand installation, stressing, removal, and replacement.

Our systems and equipment are designed to be compact – smaller anchorages are easier to handle and to install and the tight arrangement of strands in the free length reduces the diameter of cables decreasing wind loads on the pylons and foundations. Installation of the cables and stressing operations are completed with lightweight equipment that can be hand carried – freeing up valuable resources on your job for other tasks.

Bridge Armoring & Protection Systems

Many critical elements of major bridges are exposed and vulnerable to a variety of threats – both malicious and accidental. Proper surveillance and controlled access to the structure, while vital, are typically not enough to protect bridges from events like fires or a well-planned attack. To increase protection, hardening critical structural elements and protecting against fire events becomes an essential component of bridge security.

STRUCTURAL TECHNOLOGIES has partnered with leading composite manufacturer Hardwire LLC to develop customized protection systems for bridge support cables as well as other key structural elements such as pylons and piers. Depending on the threat matrix, each project’s armor and fire protection design is adjusted and optimized for peak performance.
