Tendon in prestressing
Webaxis, it is called uniaxial prestressing (longitudinal prestressing of beams). If the prestressing cables are parallel to two axes, it is termed as biaxial prestressing (prestressing of slabs). In multiaxial prestressing, the prestressing cables are parallel to more than two axes (prestressing of domes). 3.

Web28 Apr 2024 · Prestressing can be used for strengthening an existing structure and in a new construction as well [ 1 ]. There are two conventional pre-tensioning schemes: draped and straight tendon; the former scheme improves ductility more than the latter. However, due to having lower construction expenses, straight tendons are more favorable [ 2 ].
