Algorithm for calculating the loss of tendon Prestress

  • Load / Boundary
  • Intermediate level
  • 2002.12.11

The loss of tendon prestress is classified into 3 kinds; namely the loss during seating the instant loss after seating and the long-term loss.

During the seating operation the loss by instant elastic deformation of the concrete occurs due to the applied tension force. MIDAS however considers that this shortening effect has been accounted for by the prestress load. Accordingly, this loss is excluded from the calculation of prestress loss.
