Abstract:
A nonlinear finite element analysis was conducted to examine the full range of behavior of segmentally precast box girder construction with external post-tensioning tendons. A primary objective of the study was to examine the effect of dry joints (without epoxy) on the strength and ductility of box girder construction. A secondary consideration was the influence of supplemental bonded internal tendons on the behavior of the structure.
