Calculation method for corrosion damage compression bearing capacity of single-limb eccentric connection angle steel component

The invention provides a calculation method for corrosion damage compression bearing capacity of a single-limb eccentric connection angle steel component. The calculation method comprises the following steps: determining a corrosion damage type of a target angle steel component; calculating a corrosion damage coefficient and a corrosion rate of the target angle steel component according to the corrosion damage type of the target angle steel component; determining a stability coefficient of the target angle steel component according to the single-limb connection constraint type of the target angle steel component; determining the stable strength reduction coefficient of the target angle steel component according to the ratio of the free extension width of the flange of the single-leg eccentric connection angle steel component to the leg thickness after corrosion; and according to the corrosion damage coefficient, the corrosion rate, the stability coefficient and the stability strength reduction coefficient of
