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. Its predominant failure mode was detected as the punching shear by repetition of wheel loads. In this paper, the authors have derived punching shear strength formulas for fatigue strength evaluation. These formulas were induced by the concrete cracking pattern and failure mode of mid span part between supporting girders and overhanging part specimens for wheel trucking tests.
