The rate of corrosion of the rolled steel beam was determined using a standard expression for extreme marine environment. Limit equations were used to evaluate the shear performance, deflection, and resistance moment of the rolled steel beams during their design period. The exposure to corrosion was evaluated using the First Order Reliability Method (FORM) in MATLAB with FERUM Version 4.0 (Finite Element Reliability Using Matlab). An increasing decline in the shear, resistance moment, and deflection was observed as the cross sectional area decreased due to corrosion, which is consistent with experimental data. However, it was also noted that the design formulation is robust enough to exceed the design life prediction in the code.
