| Abstract: | The bonding properties of fiber reinforced polymer(FRP) rebars in concrete are experimentally studied through direct pullout and beam tests.The effects of concrete compressive strength,embedded length reinforcement diameter as well as concrete cast depth on bonding properties are investigated.The mechanism of the stress transferred from FRP rebars to concrete is analyzed.Finally,the design guideline for calculating the anchorage length of FRP rebars is recommended. |
| |
| Keywords: | FRP rebar concrete bonding strength anchorage length |
