Abstract:

One significant structural element that requires a lot of concrete is a slab. The thickness of the slab will increase if there is a heavy load on it or if the spacing between columns is not shortened. Overall, thicker slabs require more concrete and steel, which raises the slab's self-weight.

This paper presents the Finite Element Method (FEM) for analysing the failure pattern of rectangular slab , circular slab and triangular slab  with same loading condition . Non-Linear static analysis is carried out using ANSYS Software. It has been done to bring the maximum central deflection in Triangular and Rectangular plates closer to the mesh's increased fineness. Yield line theory and FEM (ANSYS software) findings have been compared traditional outcomes. Engineers were obliged to rely on empirical calculations because it was difficult to determine displacements and stresses in reinforced concrete analytically. Concrete is composed of a number of materials, including creep, and shrinking affected its deformations. During their service life loadings, the concrete slab and other delicate materials show growing bending as a result of mechanical and environmental conditions. For this project, Ansys software is used to study various slab shapes.
