With an aging infrastructure in the United States it is becoming more pressing to understand corrosion and the effects it has on structures. This knowledge will allow structural inspectors to determine the best course of action to take when dealing with a corroded member and insight so as to not take a member out of service prematurely. There are many types of corrosion that effects steel structures the form that is being studied in this report is uniform corrosion. Uniform corrosion occurs when the corrosion process attacks the surface of the steel uniformly thinning the material. This report looks at the effect uniform corrosion has on built up I sections subjected to a bending moment, and the reduction in moment strength associated with a percent loss in cross sectional area. To accomplish this lab tests were conducted on beams that were corroded in a controlled environment. With a known reduction in cross sectional area the beams were exposed to a bending test and the results were compared to moment values calculated using equations present in the American Institute of Steel Construction Steel Manual. In addition to bending tests tension tests were conducted on non-corroded tension specimens, corroded tension test specimens and corroded specimens that the corrosion byproduct was cleaned off by a chemical process. Finally finite element models were created to as another check and to see if the corrosion process could be modeled by assuming idealized uniform loss in area from corrosion
