Post-tensioned (PT) concrete structures consist of high-strength steel tendons placed in concrete that are tensioned after the concrete has gained sufficient compressive strength (i.e. hardened). Tensioning the tendons provides a precompression force in the concrete, which can result in smaller ...

Once the desired stress is attained, the rebars are secured in their stressed position by casting concrete around them. After the concrete solidifies, the jacks or devices are released, transferring the stress to the rebars. In post-tensioning, the rebars are initially placed in the concrete st...

Anthony Bridge is a truss, but the project team proposed adding a posttensioned concrete bottom chord to the steel truss in order to reinforce it. The project team made this choice because one bridge in Minnesota has collapsed in 2007, and the engineers wanted to lessen the fracture-critical ...

Post-tensioning imparts an internal compressive force into the concrete. This increases resistance to deflections and cracking caused by expansive soil problems such as lift, shrinkage, or swelling due to temperature or moisture changes. Providing better quality with lower costs, CMC Cable’s post-te...
The bars are used to anchor inserts, anchors, or post-tensioning tendons into concrete to prevent the concrete from "blowing out" at a free edge. The name hairpin refers to the similarity in appearance and function to the pins used to hold one's hair in place. Upvote 0 Down...
