ABSTRACT
Metal structures are widely used in modern construction. Therefore, it is essential to know how long they can last. We propose to determine their residual operating life by the corrosion rate and corrosion resistance criterion. With these methods, we can determine the residual operating life using various dependencies. Therefore, it becomes possible to evaluate and check the obtained results independently. We also present an algorithm for evaluating the obtained values and assigning the final value of the residual operating life.
