A comparative study of mechanical properties of S355 steel and S235 steel under elevated temperatures.

Abstract

Steel has been utilized in the construction sector for a long time. Steel research and development is ever-expanding as a result of steel being one of the most extensively available and frequently utilized construction materials, as well as its application in other sectors. We know that exposure to high temperatures results in steel losing a lot of its strength. There is little that can be done to stop steel from losing this strength but having a clear and accurate description of its properties lowers the risk of fatal failure to arise.

This paper compares S355 steel and S235 steel properties under elevated temperatures using a tensile testing method in the IMBM laboratory at the University of Stavanger. The results show a clearer picture of the properties of the two different types of steel after being subjected to high temperatures. This comparative study aims to give a more accurate design value for these specific types of steel due to an imprecise design value in the European design standard for structural fire design of steel structures EN 1993-1-2. To get trustworthy results in more complex procedures, such as a finite element analysis, one must use accurate material measurements.
