Pullout tests of afrp reinforced concrete using acoustic emission technique

Chen, R.H.L. / Sami, Z. / GangaRao, H.V.S.

A preliminary study to monitor the bond behavior between Concrete and Aramid Fiber Reinforced Plastic (AFRP) bars using Acoustic Emission (AE) technique is conducted. Five specimens with AFRP bars placed axisymmetrically in conrete cylinders were subjected to pullout tests. Acoustic emission activity was monitored using two AE sensors per AFRP bar on both sides of the concrete cylinder. Test results indicate that location of AE sources can indicate the debonding interfaces between concrete and AFRP bar. Thus, bond stress distribution between concrete and AFRP bars is estimated.
