ABSTRACT
The corrosion of studs in the negative moment region of steel-concrete composite girders in chloride environment was studied. In this paper, the erosion process of chloride ion in the stud shear connector was simulated by using finite element models. Finite element models with the crack width and depth as variable parameters were established, and the effects of different crack widths and depths on the penetration of chloride ions in the stud shear connector were studied by comparing the analysis results. The results show that the chloride ion concentration near the stud decreases from the stud head to the stud root. The width and depth of the cracks have significant effects on the erosion of chloride ions in the stud shear connector, which must be carefully considered in the design of steel-concrete composite girders.
