This paper presents the behavior of RCC columns with PVC tube as external confinement with and without external links. An experimental investigation was carried out to predict the load carrying capacity, energy absorption capacity and confinement of columns with and without external links. The parameters investigated were spacing of the external links of 90 mm c/c and 180 mm c/c. Columns were tested by using loading frame. It is observed that depending upon the spacing of external links along with the PVC tube confinement, the load carrying capacity of the column becomes increased. The spacing of external links along with the PVC tube confinement plays an important role in enhancing the load carrying capacity of the column. Columns with external links spaced at 180 mm apart showed an increase in the ultimate load carrying capacity by 140% to 150%, and columns with 90 mm spacing of external links exhibited an increase in the ultimate load (at which failure occurred) by about 180% to 184%.
