Abstract
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. One of the predominant fatigue damage modes of the composite deck was detected as shear-off failure of the studs by repetition of wheel loads. In this paper, three-dimensional finite element analyses of mid span part and overhanging part specimens for wheel trucking tests were conducted to evaluate characteristics of shear forces of the studs. Furthermore, comparison between analytical values and experimental results of these specimens, fatigue strength of the studs was investigated.
