چکیده انگلیسی
A total of eleven loading tests were conducted to study the influence of local corrosion on the behavior of steel I-beams subjected to end patch loading. The test parameters included: corrosion pattern (web corrosion, and flange corrosion), corroded length (100Â mm, 200Â mm, and 300Â mm), corroded thickness (4Â mm, and 6Â mm), and length of the bearing plate (80Â mm, and 160Â mm). Comparisons have been made between the test results and the predicted strengths using current design codes: AISC, AASHTO, and EN1993-1-5. The test results indicate that the web corrosion has a more detrimental effect than the flange corrosion. The behavior of the steel I-beams (e.g., ultimate load, web deformation, and flange and web's strains) is significantly affected by the corroded thickness of the web. However, this is mainly related to the web corrosion within the flange diffusion range. In general, the web local yielding provisions in AISC and AASHTO give the best prediction.
