摘要：
Ultimate strength of steel tubular members with general corrosion or spot corrosion under coating paint, subjected to pure compression or bending is investigated. Surface roughness of tubular specimens with general corrosion taken from the splash zone is measured, and the ultimate strength are examined both experimentally and numerically. Spot corrosions as a result of degradation of coating paint are modeled based on the existing related test results and ultimate strength is examined numerically. Based on the obtained results, the applicability of existing design formula for the evaluation of residual strength of corroded steel tubular members is examined.
