Minimizing the occurrence of factors affecting the acceleration of degradation process of steel bridge structures

The paper describes typical damage of steel bridge structures and in particular structures located in highly urbanized areas. These objects are especially prone to a number of factors that accelerate their process of degradation, such as air pollution, stray currents or a large number of load cycles. The main aim of the authors was to formulate general recommendations, the implementation of which may contribute, directly or indirectly, to slowing the degradation process of steel bridge structures. In addition, these recommendations may increase the safety and comfort of road users and extend the safe operation of these structures. Recommendations that cover the phases of the design, construction and operation of bridge structures were formulated on the basis of many years of experience, which was acquired during inspections of steel road and rail bridge structures.
