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. 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.
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.
Structural 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.
