3 Qantas Arrivals/Departure Hall, Sydney B A R S Y S T E M S VSL have been manufacturing and designing bar systems in Australia for use by the construction industry since These have proven to be one of the most popular tools of Engineers wishing to induce and control loads and forces in structures. The systems range from High Tensile Cold Worked Stressbar to Low Tensile Architectural Tendons, all with compact and easy to assemble fittings. A range of diameters is available to give a wide selection of tendon forces. The pre s t ressing force is anchore d at the end of the bar by a rolled thread, nut, washer and bearing plate. Where necessary bars can be joined with threaded couplers, and clevis fittings may be used where pin connections are re q u i re d. The VSL bar system complies with the requirements of the Australian Standards.

4 A P P L I C AT I O N VSL bar systems are ideal for the economic application of post tensioning forces on relatively short tendons. Through the use of threaded connections and anchorages they are simple to use and lend themselves to many applications.

C O R R O S I O N P R O T E C T I O N All bars and fittings must receive protection when installed under permanent conditions. In normal concrete construction the use of galvanised duct, injected with grout, provides good protection. Anchorage recesses must also be filled with cement mortar to protect the ends. Bars When bars are used in an exposed environment,one of the following coating systems may be used. Single coat of inorganic zinc Three coat epoxy paint system Greased and sheathed in poly tube A combination of the above systems may also be specified. Consideration must also be given to the threaded ends to ensure correct installation of fittings after coating. Fittings Fittings may be treated as above but with preference given to galvanising. Temporary Bar Anchors Anchors used in a temporary environment may be used without protection apart from grout cover. Permanent Bar Anchors These anchors require installation into corrugated polyethylene sheathing to provide multiple levels of protection. This is accomplished by the internal grout and sheathing barrier. Additional protection may also be used by incorporating the above bar coatings. 4
