Bonded Multistrand Post-Tensioning

 
 
 
 

STRUCTURAL TECHNOLOGIES tailors VSL products to meet a variety of unique project specifications, including:

  • Encapsulated for optimum corrosion protection
  • Couplers to connect tendons that are already installed
  • Inspectable for post-grouting inspection
  • Electrically Isolated to eliminate corrosion or monitor tendon integrity
  • Loops where there is no access to the dead-end
 

Extensively used in bridge and transportation structures, bonded multistrand post-tensioning systems have also 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.

When bonded multistrand post-tensioning 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 resulting in cost savings.

STRUCTURAL TECHNOLOGIES, a Structural Group company, is the exclusive designer and manufacturer of VSL post-tensioning and construction systems in the United States.

Manufacturing & Material Supply

Post-Tensioning ManufacturingSchedule is critical to the success of your projects. STRUCTURAL TECHNOLOGIES works diligently to manufacture and deliver our products on time. All of our manufacturing facilities in the United States are certified by the Post-Tensioning Institute’s (PTI) Plant Certification Program to ensure the highest quality fabrication of materials and equipment. Dedicated project coordinators and project managers work closely with contractors and engineers to ensure accurate and timely delivery of material, equipment and services.

 

 

 

Project Coordination

Project CoordinationFor post-tensioning projects, STRUCTURAL TECHNOLOGIES utilizes our proprietary PT Builder software that allows digital recognition of post-tensioning drawings and automatically generates tendon schedules – showing identification tags, quantities, lengths, color codes and tendon elongations. PT Builder also generates detailed schedules detailing the heights and quantities of the chair supports. Shop fabrication orders are automatically generated and fed directly to computerized strand cutting lines resulting in superior accuracy and efficient installation.

 

 

 

Installation Support

Post-Tensioning Installation SupportSTRUCTURAL TECHNOLOGIES’ highly trained field leadership provides expertise in all areas of post-tensioning installation services. For critical activies such as stressing and grouting, our technicians are certified by the Post-Tensioning Institute (PTI) and the American Segmental Bridge Institute (ASBI). Our staff is available to provide on-site training and supervision or to install systems. Available equipment is expertly maintained and calibrated by skilled mechanics prior to jobsite delivery.
