Stiffness degradation of high-performance steel (HPS) beams with local shear-span corrosion is studied by experimental investigation and numerical analysis. Six beams subjected to various level of local corrosion damage are designed. 3D scanning technology is employed to analyze the geometric features affected by the corrosion damage. Flexural tests are carried out, and the effect of the local corrosion on the stiffness degradation is analyzed. Numerical models considering corrosion characteristics are established. By using the FEA models, parametric analysis is carried out to investigate the ...
