Finite Element Analysis of RCC Columns and Footings Using COMSOL Multiphysics
Abstract
Reinforced concrete columns and footing are important parts of a building because they help move the load from the superstructure to the function. Traditional analytical design methods are generally based on fundamental assumptions, including linear elastic material properties and uniform stress distributions, which might not represent the real behaviour of structures. A sophisticated technique for analyzing structures, finite element analysis (FEA) may replicate the actual behavior of structures through nonlinear material features, boundary conditions, and load transmission processes. COMSOL Multiphysics software is used in this study to perform a finite element analysis of reinforced concrete columns and footings. Structural responses, including axial stress, axial load, deflection, axial thrust, and base pressure, are calculated and compared with the analytical solution based on conventional reinforced concrete theory. The percentage error approach is used to validate the outcomes of the COMSOL Multiphysics software. The finite element model is validated by the findings, which show very slight variations.Using COMSOL Multiphysics software,which is a good tool for analysing reinforced concrete structures,can make structural analysis more accurate.
