Selecting the optimal method for strengthening reinforced concrete columns
Abstract
Selecting the optimal method for strengthening reinforced concrete columns
Incoming article date: 14.07.2025The article presents an analysis of methods for strengthening reinforced concrete columns without changing the original design scheme. The calculation of reinforcement with a metal collar, a reinforced concrete collar, using prestressed struts and reinforcement with composite materials under central and eccentric compression is performed. A comparative analysis of the technical indicators of the considered reinforcement methods is made. A strategy for selecting a method for strengthening reinforced concrete columns is formed. An analysis of the optimal areas of application of various methods for strengthening reinforced concrete columns shows that the choice of a specific technology should be determined by the nature of their stress state depending on the magnitude of the eccentricity of load application. This study confirms that there is no universal "best" method for strengthening reinforced concrete columns; each of the considered methods has its own advantages and disadvantages. The results allow choosing optimal solutions based on the criteria of efficiency, reliability and cost-effectiveness.
