In order to study the effect of marine corrosion on the hysteretic performance of Q690 high strength steel, By artificially accelerating the simulated corrosion method in the room, Obtained Q690 high strength steel corrosion test piece, Carried out topography scan and cyclic loading test, The influence of different degrees of corrosion on the hysteretic behavior of high-strength steels was analyzed. The relationship between the parameters of the hysteresis curve model of the corroded steel and the mass loss rate was established. The results show that the seismic performance of Q690 high-strength steel decreases as the degree of corrosion increases. After 100 days of corrosion, the hysteresis of the test piece can be reduced by 15.2%. The ultimate tensile strength was reduced by 14.6%, The pit depth reached 600 μm. The Ramberg-Osgood model can better simulate the mechanical properties of rusted high-strength steel under cyclic loading. By comparing with the test results, It shows that the constitutive model of rusted high-strength steel has good practicability.
