Abstract

ABSTRACT Li, Y. and Dong, F., 2018. Fire resistance of steel bridge considering damage of marine environment. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 442–447. Coconut Creek (Florida), I SSN 0749-0208. The traditional method does not consider the fire resistance of steel bridges subjected to chloride ion corrosion. Therefore, a method for studying the fire resistance of steel bridges under consideration of the damage of marine environment is proposed. First of all, the thermal and mechanical properties of steel bridges at high temperature are analyzed. Then, the corrosion mechanism of steel bridges considering the damage of marine environment is analyzed. Finally, the maximum width of initial crack generated by chloride erosion is acted as the damage index for rapid chloride corrosion test, and then the fire test is performed for components of different damage degree. The experimental results show that the c...
