Abstract

This paper presents the experimental results of a full scale spliced PSC-steel-PSC hybrid I-girder with a length of 40m. The spliced hybrid bridge can be an effective system in both structural and economical aspects, whereas it needs a joint which connects PSC and steel segments at a site. In this study, to connect PSC and steel segments, a new type of joint is proposed. The proposed joint consists of perfobond rib shear connectors, encased concretes, and steel sections with a small length; this joint type is basically verified through the small scale beams tested by authors' previous researches. First, the PSC segment with a proposed joint and the steel segment are fabricated in a factory. Then, these segments are transported to a test site and assembled into one girder by bolting connection. The experimental results show that the spliced PSC-steel- PSC hybrid girder with the proposed joints has a sufficient strength, ductility, and stiffness without giving the failure of the joint.
