Abstract
Recently, many types of hybrid structures with steel and concrete materials have come to be increasingly developed.Conugated steel web PC box bridge is one of these hybrid structures.On the other hand, this type of bridge has not been adopted yet for railway bridges, while these bridges have been constructed forhighway bridges.In this paper, we aim to confirm fatigue durability of joint part connecting the corrugated steel web plate with the concrete slab.The static and fatigue loading tests were carried out under in-plane cyclic bending.As a result, it was clarified that both of two diffbrent types of jointpart, called constraint reinfbrced bar type and flat bar type, had enough fatigue durability.
