Composite constructions are commonly used because to their high specific strength, structural stiffness, and light weight. A composite beam has a concrete slab on top and a steel beam underneath with an I-shaped cross section. A three-dimensional composite beam is simulated using finite element analysis to study the change in thickness of concrete slab and steel section exposed to uniformly distributed load. On both extremities of the construction, the support requirements are illustrated as fixed beams. A comparative study using steel I section beams on three different concrete slab thicknesses of 80, 100, and 120 mm is presented. Total deformation, maximum primary stress, shear stress, normal elastic strain, and strain energy are shown in the composite T beam at midspan. It further argues that longitudinal compressive stresses in concrete slabs have a non-uniform stress distribution across the cross section, resulting in positive bending moments. Shear stress across sections must be measured to ensure that concrete components act compositely. The advantages of composite sections for various types of structural components in terms of construction time and cost is the primary motivation for numerical modelling of composite sections.
