Holding Down Bar Systems
Restraint system for bridges and viaducts
High Tensile Holding Down Bars are a special application for smooth Post Tensioning bar systems for the connection between steel and concrete elements or concrete to concrete elements.
The bars are typically used vertically for the holding down of structures or structural elements to concrete foundations.
Each bar tendon is typically terminated via a nut bearing onto steelwork or a steel plate. In order to eliminate bar stretch and hence movement under externally applied loads, the bar is usually tensioned using a hydraulic jack.
