overstretching

The stressing of steel tendons to a value higher than designed for the initial stress; this is done (a) to overcome frictional losses, (b) to overstress temporarily the steel to reduce creep in the steel which occurs after anchorage, and (c) to counteract the loss of prestressing force that is caused by the subsequent prestressing of other tendons.
