Increase of waste FRP(fiber reinforced plastics) has caused environmental problems. Recently, the technology of making concrete-reinforcing fibers from waste FRP was developed and experimental tests were performed to study the structural performance of concrete members strengthened with recycled fibres. The purpose of this study is to investigate the effect of recycled glass-fibers from waste FRP on the seismic performance of reinforced concrete beam-to-column joints. Experimental tests were performed for two reinforced concrete beam-to-column joint specimens with the same reinforcements. One joint was strengthened with recycled fibers at a fibre volumn fraction of 1.0%. Cyclic-loading tests were performed on the specimens. Test results showed that use of recycled fibers increased the seismic performance of the reinforced concrete beam-to-column joint significantly.
