Case Study Contruction of Post Tensioned Bridge Deck Slab

Abstract

Pouring in-situ concrete on top of beams in rural bridge designs is a frequent design method that serves to both disperse weight and connect together all of the beams in the bridge. Pouring concrete on the job site, however, presents a greater danger, and most contractors try to avoid doing so. One such technique for securing beams is called transverse post tensioning. The purpose of this paper was to explore how transverse post-tensioning bars behave while providing load distribution between beams and, finally, to remark on how successful they are in comparison to in-situ poured decks. At this point in time, the industry has not conducted a comprehensive investigation into this subject in order to appropriately design post-tensioning. In today's business world, estimations that are on the conservative side are employed. The standard procedure, which is followed now, is to put fifty percent of the design load on the beam at the point where the load is applied in their design assumptions, which are rather high.
