Abstract :In this study, improving the behavior of short column region by means of higher energy consumption and higher shear load carrying capacity is aimed. For this purpose, a special kind of concrete with high steel fiber ratio (SIFCON) is used for coating of column and placing rubber dampers around the short column region was proposed. As a result, it’s seen that; the SIFCON coating increased the shear force carrying capacity of short column by 2,18 times when compared with non-retrofitted specimen, whereas additional rubber dampers around the short column region increased the total load carried by 4 times. Also, the energy dissipation of the region increased by 2,02 to 2,82 times when compared with non-retrofitted situation. As a result, it was seen that, with a practical approach it is possible to improve the behavior of short columns.
