Analysis of continuous beams prestressed with localized tendons

In this paper, the use of localized tendons to prestress statically indeter minate structures is examined. To determine the prestressing moments produc ed by localized tendons, the fixed-end moments should first be computed. Eq uations and charts are presented to show the effects on these moments of va rying the geometric parameters that define the localized tendon profile. Th ese equations and charts are helpful for selecting the values of the parame ters before using computer programs to obtain the resultant prestressing mo ment at any section of the structure.
