Iterative Prediction on Friction Loss Parameters of Prestress Tendon

Abstract:

Because of the more sophisticated fiction loss for prestress of space curve tendon than that of the beeline one. The key parameters in the attrition loss for space curve tendon are predicted and regularities of practical distribution can be simulated in this paper simultaneously, by means of the iterative method based on the attrition loss for prestress test of a long-span continuous rigid frame bridge. The predicted parameters can also provide some reference in the calculating the attrition loss for prestress of the space curve tendon in other bridges.
