This paper experimentally investigates the seismic performance of RC columns retrofitted by Super Reinforcement with Flexibility (SRF). A total of three specimens with a scale factor of 1/2 were constructed and tested in order to assess the structural behavior of the retrofitted RC columns. One specimen was a non-seismically designed column without any retrofitting method while others were retrofitted with either one or two layers of SRF by using urethane adhesive. The static cyclic testing with a constant axial load was conducted to assess the seismic performance of the retrofitted RC columns. It is concluded that the SRF retrofitting method increases the strength and ductility of the RC columns and can also impact on the failure mode of the columns.

In this study, the behavior and ductility characteristics of fiber reinforced concrete was experimentally conducted under high and low temperature conditions. The results showed that the ductility index was increased with temperature increase.
