Abstract

Structural members such as beams and columns may undergo substandard detailing of steel reinforcement, deterioration of concrete and steel under severe environmental attacks such as earthquakes, fire accidents and marine exposure. In such cases replacement of full structure will be expensive due to material and manpower and also creates an impact on culture considering heritage structures such as temples. The other solution for this problem is to retrofit these damaged and deteriorated structural members to meet the exposure conditions. Repair and rehabilitation of Reinforced Concrete (RC) structures can be generally carried out by conventional techniques such as concrete and steel jacketing. Now-a-days some advanced retrofitting methods such as external prestressing and Fiber Reinforced Polymer (FRP) composite wrapping etc. have become popular due to their excellent properties such as corrosion resistance, durability, ease of application and adding less dead weight to the structure without affecting the aesthetic appearance. The aim of this paper is to provide a overview of experimental studies and analytical models available for retrofitting of RC columns using FRP composites. This paper focuses on retrofitting of RC rectangular columns which is most common in heritage structures without modifying the shape of the cross section. The paper also highlights the design guidelines and recommendations available for retrofitting of RC columns with side aspect ratio greater than 2.0 and identifies potential research gaps for further research in the field of retrofitting of RC columns.
