Study on Behavior of Steel, Monel and Inconel at Elevated Temperature

In recent times, fire safety has become important in structural design due to increased fire damage to the properties and loss of lives. The analysis of structural members in a compartment in a steel framed structure subjected to fire attack is often difficult leading to the combined complexity of the material degradation and of the actions induced by thermal strains. The deformations of the steel structures will be caused due to many reasons and it mainly depends upon material properties and temperature conditions. Hence it is important to assess the behaviour of structures with different material properties under elevated temperature. This paper studies the behaviour of steel beam, which is a part of a thermal power plant structure subjected to elevated temperature on a framed compartment by finite element method. The study involves two –sided, three –sided and four –sided exposure conditions. A profound variation in responses is observed under the combination of thermal action and material properties. This paper also presents a review on responses of characteristic properties of structural steel and its alloys like Monel and Inconel at elevated temperature.

Keywords- Elevated temperature, Finite element analysis, Material degradation, Steel structures, Temperature conditions, Thermal stain, Thermal expansion and Thermo-mechanic behavior.
