Parametric Analysis of Steel beam using Roark’s Computer Aided Design

Steel is widely used in construction and other applications because of its high tensile strength and low cost. Iron is the basic component of steel. Composition of steel mainly consists of iron and other elements such as carbon, manganese, silicon, phosphorus, sulphur, and alloying elements. It was observed as the elastic modulus of high strength steel and iron steel ,the deflection of the steel in case of the cast iron compared to the 5% less while using high strength steel by roak's analysis .A large number of elements in wide ranging percentages are used for the purpose of alloying of steels. Variations in chemical composition of steels are responsible for a great variety of steel grades and steel properties. Each element that is added to the basic steel composition has some effect on the properties of the steel and how that steel reacts to the processes of working and fabrication of steels. The chemical composition of steel also determines the behaviour of steel in different environments. Steel standards define the limits for composition, quality and performance parameters for various steel grades. Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. The deflection of the iron steel l was obtained based on the Roark analysis less compared to other type of steel. The mechanical properties of steel govern directly the deflection steel beam and the value reducing continuously to the fixed l end of the steel beam. The deflection of the high strength steel was obtained based on the Roark analysis was 5% at the 12.0m from the fixed end of the beam and the value reducing continuously to 10% at the distance 9.96m from the fixed l end of the steel beam compared to iron steel.
