Abstract—In order to study the corrosion resistance and cyclic mechanical properties of the new domestic Q960 highstrength steel, this paper conducted cyclic loading tests on 7 Q960 high-strength steel cyclic material properties specimens under 7 different loading regimes, and 10 Q960 high-strength steel cyclic material properties specimens were subjected to different degrees of salt spray corrosion tests and cyclic loading tests after corrosion, and the skeleton curves and energy dissipation coefficients of the steel before and after corrosion were extracted, and the cyclic mechanical properties of the steel before and after corrosion were The cyclic mechanical properties of the steel before and after corrosion were evaluated. The results show that the cyclic softening phenomenon exists under cyclic loading, and the steel has good load carrying capacity and cyclic energy dissipation capacity before and after corrosion, which can be used in corrosive environments and in structures with seismic requirements.
