Abstract:: In order to study the variation law of stress flow of bridge steel Q345 with strong acid corrosion, 18 Q345 bridge steel specimens were immersed in 36% industrial hydrochloric acid for 0, 1, 4, 12, 48 and 72 h, respectively. The engineering stress-strain curves were obtained by quasi-static tensile test.The true stress-strain curve before necking was fitted by Origin software, and the elastic-plastic constitutive relation of strong corrosion bridge steel Q345 based on J-C model was obtained.On this basis, ABAQUS finite element model was established and the damage evolution of flexible metal was added to simulate the stress flow law and necking failure of steel plate, and the influence of different strong acid corrosion time on the mechanical property degradation of bridge steel Q345 was analyzed.The results showed that the elastic modulus of bridge steel Q345 with corrosion rate of 0.53%, 1.22%, 2.47%, 4.12% and 4.98% decreased by 1.26%, 2.36%, 4.04%, 7.01% and 10.93%, respectively, and the yield strength decreased by 0.61%, 2.61%, 3.56%, 5.37% and 6.82%, respectively, the ultimate strength decreased by 0.42%, 2.31%, 3.57%, 4.58% and 6.42%, respectively.The results showed that the decline rate of mechanical properties of bridge steel plate was relatively slow when corrosion time exceeded 12 h. J-C constitutive model could well simulate the stress flow of bridge steel under strong corrosion. The ductile degradation behavior of strongly corroded steel could be accurately simulated by the flexible damage evolution.
