In Japan, a steel-plate concrete composite deck which is connected concrete and a steel-plate with shear studs, is called Robinson type. In order to decrease deflection of the steel plate when fresh concrete is casting on, the steel plate is stiffened with steel strips. In recent years, the composite deck is applied to many high way bridge decks. The objective of this paper is to propose a performance-based design method for the composite deck that founded on the results of researches conducted by the authors. Specifically, performance and functional requirements for bridge decks are considered, and design traffic loads and partially safety factors peculiar to bridge decks for performance verifications are evaluated. Furthermore, examples of performance verifications of actual composite decks are carried out. In conclusion, the proposed design method enables the composite deck within a long span range to reduce its thickness approximately 20% compared with the standards of conventionally design method.
