 Strengthening of existing column using steel plates: Finite Element Analysis

Abstract

Concrete buildings are deteriorating, demanding their demolition or rehabilitation. However, structures with significant value cannot always be rebuilt. It requires restoration and repair. Non-destructive tests (NDT) can be used to evaluate the residual strength of aging structures, allowing for the selection of the best restoration options. The Finite element method can be used to verify whether the repair strategy we chose can be suited or not. Results from the FEM reveal characteristics of stress, shear and deformation of structural members that could withstand in their damaged state as well as their behavior after applying repair procedures to the existing load. This article comprises a column demonstrating the current condition and another with its steel plate encasement on the periphery of varying thicknesses or concrete jacketing which give better results as a repair measure supporting the current structural load.
