Experimental measurement of environmental actions on structural steel members

Abstract Increased activities of the environmental actions become the worldwide problem considerably influencing serviceability of the engineering constructions. Aggressive environmental causes the massive material degradation of constructions, therefore it is necessary to predict their influence on reliability and mainly durability of structures. Corrosion aggressiveness of the atmospheric environment is classified by the corrosion rate represented by the thickness losses of structural steel leading to decreasing the resistance of steel bridge members. This paper presents the research of corrosion characteristics of steel bridges, and results of experimental measurements in-situ.
