Structural Retrofitting of Corrosion-Damaged Columns in Reinforced Concrete Buildings : A Case Study in KFC Commercial Restaurant Banda Aceh, Indonesia
Year: 2024
Type: conference-paper
Abstract: The aim of this paper is to identify effective strategies and solution for damaged column due to corrosion. It investigates a case study of a commercial building in Aceh Province, Indonesia, that suffered from corrosion attack in its columns. The building’s structural deterioration was due to the corrosion of its embedded steel reinforcement, which led to cracking, spalling of concrete and ultimately local buckling. The assessment method that conducted on the existing building involved a combination of non-destructive testing, visual inspections, and laboratory analysis to assess the structural condition and identifying the necessary repairs. The structural model was developed using finite element analysis software, which utilizes a numerical method to simulate the structural response to different loads. The retrofitting strategy included both jacketing and the addition of wide flange profile columns to enhance structural integrity. It demonstrates the effectiveness of structural retrofitting in restoring the integrity of structural column damaged by corrosion with the retrofitted columns exhibiting up to 15 greater strength than the existing column. This study provides insights into effective strategies for rehabilitating structures affected by natural disasters.
