Rocking Response of AFRP Reinforced Concrete Columns with Unbonded Energy Dissipaters
In this paper, an AFRP-reinforced concrete (AFRP-RC) column is designed to dissipate energy through rocking when subjected to cyclic loads. The AFRP-RC column rocks via unbonded energy dissipaters that act as replaceable structural fuses (25.4, 32.25, and 38.1 mm) fabricated out of plain Grade 50 mild steel bars. Six columns (350 × 350 × 1524 mm) are subjected to a predetermined drift up to 4%, and loaded until failure to examine the overall column responses and effectiveness of the external dissipaters. This numerical study accounts for the material, geometry, and interaction among elements of the system. Failure of the rocking AFRP columns occur at higher drifts (>3%) as a result of the yielding of the steel dissipaters with minimal strains noted in the internal AFRP reinforcement. In addition, there are noticeable ductility and energy dissipation gains of 70% and 200%, respectively, in the rocking AFRP-RC columns compared to the conventional RC column.
