Abstract—Nowadays, corrosion on steel structures is a common occurrence. The reasons that lead to the appearance of
corrosion in structures are well-know as well as its negative impact of them. The possibility of re-use corroded steel elements
into the construction should be ascertained and how this would affect the calculation and the design of the structure. We conducted an experiment to determine how the modulus of elasticity of corroded steel specimens was changed. We applied an electrochemical accelerated corrosion method to our S355JR steel specimens. After that we tensile- tested them, we took the values from the stress-strain diagrams and calculated the module change. We also applied the stochastic way of
processing of the results. We have reached a conclusion that corrosion indicates a serious impact on the modulus of elasticity, even leading to a change of material, i.e. from ductile material,
it subsequently becomes a brittle material, which circumstance should be taken into account in the re-use of corroded elements
in their calculation and design.
