The Magnitude of Loss of Prestress Due to Relaxation of Steel
The magnitude of the loss of prestress due to relaxation of steel is in the range of
Correct answer for The magnitude of the loss of prestress due to relaxation of steel is in the range of is 2 - 8%
Loss due to Creep in steel (Relaxation of steel)
When the stresses in steel are more than half of its yield stress there is creep in steel.
The Force of prestressing falls as a result of creep in steel.
Then there is a loss of prestress.
Percentage creep varies from 2 to 8%
Creep in steel is also termed as relaxation of steel.
