This study focuses on the bond performance of ribbed type of GFRP rebar to concrete at high temperature and discusses the results of pullout tests. Pullout tests of ribbed type of GFRP rebars embedded in concrete are conducted to obtain an accurate bond stress-slip laws and also to closely observe the state of the surface of pulled-out rebars at failure to accurately categorize the mode of failure. The effect of temperature on the bond strength is Similar trends can be seen for all the GFRP rebars; relatively high bond strength is seen at room temperature. As the internal temperature increase to approximately 60~100°C, a reduction in the bond strength can be seen. |
