Abstract

Abstract:- In a composite bridge consisting of precast concrete deck elements the vertical forces will, when applied above a girder, make both girder and deck deflect simultaneously. In other places the elements of the bridge will deflect somewhat. A hinging action is needed to transfer the vertical forces so that the two elements are able to deflect simultaneously. This can be achieved either by making a joint of the type where transversal reinforcement and casting is conducted in-situ (wet joint) or by using shear keys fitted into the opposite element (dry joint). The focus of this report is on the latter, but a literature review is conducted on both. The results from those tests concluded that the shear keys used could handle a greater load than what the Swedish code stated. It was also noted that the steel reinforcement used in the shear keys were problematic to put into the right position. Because of these notations it has become of interest to investigate if the shear keys can be designed in a different way in order to optimize both size and the reinforcementused.
