Sizing Continuity Tendons in Segmental Cantilever Bridges
Publication: Practice Periodical on Structural Design and Construction
Volume 29, Issue 1
Abstract
An approximate method for sizing continuity tendons in cast-in-place segmental cantilever box girders is presented in this technical note. Variables investigated are the length of the main span, the length of the continuity tendons, and the geometry of the box girder. Results indicate that secondary moments due to the prestressing of the continuity tendons decrease as the span length increases and as the length of continuity tendon decreases. For girders with a curved soffit, it was found that the type of variation of the girder depth (e.g., parabolic, cubic) has a small effect on the magnitude of the secondary moments.
