wermac.orgstrand pushers. The strand pushers are electronically controlled and can be set to automatically stop at any desired distance. Figures 7 and 8 illustrate the strand pusher equipment and pushing operation. The post-tensioning configuration involves some large tendons which require high capacity jacking equipment. The 6,000kN capacity stressing ...

Consequently, prestressing, from both ends for a single span i.e. prestressing one-half of total tendons at one end and the remaining half at the other end is carried out to enable a even distribution and to provide symmetry of prestress force along the structure.

Since the physical properties of the prestressing steel, the curvature due to the tendon profile, the length of the ten-don, and the force that is applied (this is where calibrated stressing equipment is important) are all known values, the theoretical elongation of the tendon can be calculated.
