Web12 Aug 2024 · The post-tensioning process works as follows: First, you must install steel tendons into the formwork and position them before the concrete is placed. Steel tendons are prestressing steel cables inside plastic protective ducts or sleeves, each one with anchors on each end to transmit the forces into the structure. WebPost-Tension Type. It is used for large structural elements such as beams and transfer girders, design advantages include increased span lengths and load carrying capacity and reduced deflection. It is typically used in new construction for elevated slabs, slabs-on-grade, beams, and transfer girders, joists, shear walls, and mat foundations.
