Everything You Need To Know About Post-Tension Slabs

WebA post tension slab is reinforced with stranded steel cables that are tensioned (tightened) after the concrete hardens. The cables are slid inside a plastic sheathing, like a wrapping. This prevents the cables from touching the concrete. When the concrete has sufficiently cured, the plastic sheathing is stretched. WebIt minimizes displacement due to foot traffic. This style of concrete slab is lighter. This approach alleviates the need to reinforce the area below the slab which can be more expensive for the homeowner. Properties with expansive soil have poor load-bearing capacity. A post-tension cabling system spreads the load of the home over a wider area. WebPunching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection is always vulnerable to critical punching shear; thus, it is necessary to investigate the effect of various parameters on the punching shear behavior of the flat slabs.
