This paper presents results of testing square RC columns wrapped with FRP. The influence of the number of FRP layers and the magnitude of eccentricity were studied through experimental. A total of 16 short square reinforced concrete columns wrapped with CFRP were investigated. The columns had the dimensions 200 mm × 200 mm × 800 mm and a round corner with radius of 34 mm. 12 columns were tested under compressive loading and four columns were tested under flexural loading. Based on the number of CFRP layers, the columns were grouped into four: no-layer (unwrapped), wrapped with one layer, wrapped with three layers, and wrapped with two layers after the application of one vertical layer of CFRP straps. From each group, one column was tested under concentric loading, one column was tested under 25 mm eccentric loading, one column was tested under 50 mm eccentric loading and the last column was tested under flexure loading. The results have shown that wrapping column with CFRP composite increase the capacity and ductility of the column.
