Post Tensioned Floors
Summary
Post Tensioned Floors - Post tensioning can be used to construct jointless floors and is one method for overcoming some or all of the tensile stress that normally occurs.
Technical Information
Panel sizes can be up to 100m x 100m and there is a low risk of cracks opening as tendons cast within the slab keep the concrete in compression. However, the free movement joints around the post tensioned panels may open considerably by several centimetres.
When designing post-tensioned floors suppliers should be consulted. Consideration should also be given to the use of proprietary joint systems that can cope with potentially wide joint openings.
