摘要:Durability is a very important parameter for design of the engineering constructions because of influence due to degradation processes in the form of structural steel and reinforcement corrosion caused by the environmental actions within structure lifetime. Those degradation processes are affecting the cross-sectional and structural member resistance and deformation parameters of structure. The paper is focused on the study of the corrosion characteristics of the steel bearing structures of engineering constructions to know corrosion effects on the structural steel and to develop the methodology of design for durability.
