This study shows experimental loading tests on monolithic and spliced hybrid PSC girders with Y-type perfobond rib shear connectors. The main purposes of the study are to investigate the static behaviors of joint parts in the spliced girder and load-resisting capacity of Y-type perfobond rib shear connectors in steel-concrete composite connections. Two specimens (monolithic and spliced girder) with 10.3m length were manufactured and tested. As results of the loading tests, static it is expected that the spliced girder can be utilized effectively in practical design. In addition, Y-type perfobond rib shear connectors can be applied adequately in steel-concrete composite connections.
