Retrofitting Techniques of Columns: A Comprehensive Review of Methods and Materials

Abstract

Column retrofitting is a critical aspect of structural maintenance and improvement. It ensures that existing structures remain safe, resilient, and adaptable to evolving needs, contributing to the longevity and sustainability of the built environment. It is essential to maintain or enhance the structural integrity of buildings and infrastructure, ensuring their continued safety, resilience, and functionality. In such cases, columns may not meet current safety codes, and it becomes essential to bring them up to contemporary standards and ensure compliance with building codes. The purpose of this paper is to provide a brief overview of the methods of retrofitting, like steel jacketing, wrapping, concrete jacketing and bracing. For these advanced methods materials used in retrofitting techniques and advanced methods for column retrofitting, as it addresses various challenges associated with existing structures. Key Words: Retrofitting, Steel Jacketing, CFRP Wrapping, concrete jacketing.
