cold form steel sections are widely preferred due to the ease of fabrication and economical construction. This paper presents the results of experimental and numerical investigation of a regular cold-form steel (CFS) section to that of the section strengthened with Glass Fiber Reinforced Polymer (GFRP). Numerical analysis was performed using ANSYS and the results are compared with the experimental results and literature study. From the results, it is proposed that the concept of strategically

Local bucking was arrested and the columns were able to take 50% more load before reaching the critical yield point. Hence it is recommended to strengthen the CFS columns where ever dimensional restrictions are not present.
