Abstract

The ABAQUS software was used to study the effect of non-uniform corrosion on the reliability of the new steel-concrete composite girder bridge. The non-uniform corrosion mechanism was analyzed, and the formation process of the pitting corrosion pit was known. Combined with Python programming, the random etching pit of the structural floor was established, and the stress of the steel bottom plate of the new steel-concrete composite beam bridge before and after corrosion was explored, and it was found that the stress of the steel bottom plate in the middle span under non-uniform corrosion increased by 18.2% compared with the non-corrosion. Further calculating the reliability index of the bridge before and after corrosion, all met the requirements of the specification, and it was found that the reliability index of the new steel-concrete composite girder bridge under non-uniform corrosion was reduced by 15.5% compared with the non-corrosion.
