Abstract – Due to the recent earthquake, the need for retrofitting and renovation is essential for existing structures. Nowadays, various methods have been applied to the local and general retrofitting of RC frames. In this paper Finite element analysis of RC frame retrofitted with the LCF system were done using ANSYS workbench 2021 R2. In this, analysis of various models of LCF link beam and comparison of external and internal retrofitting and replacement of steel link column with CFST link column is also performed. In this project, the design of LC frame members for retrofitting of RC frame using proposed simplified equations are investigated.
Key Words: LCF, Retrofitting, CFST link column
