Abstract: Fabricated hollow slab bridge is commonly used in China. It is indicated that the hinged joints between hollow slabs are easily damaged. Especially under the erosion of chloride salt, the destruction process of hinged joints will be greatly exacerbated. In this paper, deicing salt environment was simulated in the lab to corrode the commonly used hinged joints. According to static load test results, hollow slab coordinated working coefficient is explored and its calculation formula was established. Meanwhile, the analysis of influencing factors on coordinated working performance of hinged joint was carried out. Finally, the reasonable and practical of coordination working coefficient was proved.
