Paper Title:
Calculation of Incremental Force of External Steel in Simply Supported Externally Prestressed Beams
  Abstract

Considering the relationship of displacement and turn angle in anchorages and deviators between the externally prestressed steel and concrete beam under the action of load in simply supported externally prestrressed beam, equations on solving the incremental force in externally prestressed steel are established. The presented novel approach and the train of thought can be easily extended to analyze time-dependent effect for externally prestressed beams. The example shows that the theoretical values based on the presented formulae are agreeable with the results obtained by other methods.
