Abstract
Corrugated steel plates have been utilized widely in engineering structures, such as underground utility tunnels, web of steel beams, underground pipelines, and shear walls. The influence of corrosion on the buckling capacity of corrugated steel plates differs from that of flat steel plates. A numerical model of corrugated steel plates with random corrosion is initially established and validated using theoretical results. The influence of pitting corrosion on the shear capacity of corrugated steel plates is investigated through stochastic numerical analysis. The influences of geometric parameters, including pitting size, plate thickness, and corroded thickness, on the shear capacity of randomly corroded steel plates are also investigated. In addition, the changing trend of shear capacity along with mass loss ratio is derived.
