The experimental program was conducted on a pattern of steel beams and combined the steel plates together. The study focuses on analyzing the behavior of curve (P-δ), whether the bearing capacity of corroded steel beams meet the requirements of using or not, how destructive position appears, function of structural instability and assessing the level of corrosive structure in the study at the same time. The experimental results also evaluating the working behavior of shaped steel beams over time. This method partly supports faster corrosion research to the artificial creation of a mechanically corroded surface, corrosion characteristics and behavior of corroded steel beams, such as force, deflection, deformation, damage, and stability through time, depth, and corrosion distribution parameters, are analyzed and evaluated in a detailed. Additional documents serve to inspect, evaluate, and design corroded steel structures. Since then, it can be evaluated the safety of steel beam structures in construction from being corroded over time. Keywords: Artificially
corroded steel beam
flexural behavior
prediction.
