Revitalizing Infrastructure: Assessing Concrete Jacketing for Reinforced Concrete Column Rehabilitation

Abstract

The rehabilitation of deteriorating civil engineering infrastructure, encompassing bridges, buildings, columns, beams, supporting beams, marine structures, and roads, presents a formidable challenge in contemporary engineering practice. As society's demand for upgraded infrastructure escalates, the imperative to address deteriorating structures becomes increasingly urgent. Consequently, the rehabilitation of existing infrastructure has been identified as a paramount concern warranting immediate attention. Among the myriad techniques employed, retrofitting columns with concrete jacketing stands out as one of the most prevalent methods for enhancing column strength. This investigation delves into the efficacy of concrete jacketing as a means of revitalizing reinforced concrete columns. The results evince a substantial augmentation in column capacity following retrofitting, underscoring the potential of such methods to bolster the load-bearing capabilities of reinforced concrete columns. Furthermore, the analysis reveals a more uniform stress distribution in retrofitted columns compared to their unmodified counterparts, thereby mitigating issues related to uneven stress distribution. In summation, the findings underscore the considerable promise of concrete jacketing in fortifying the strength, structural integrity, and longevity of deteriorated infrastructure.
