Abstract: This study investigates the cyclic behavior of precast fiber‐reinforced concrete (FRC) columns with recycled concrete powder (RCP) through experimental and numerical approaches. Six column specimens were designed and tested, including four precast FRC columns, one cast‐in‐place FRC column, and one precast normal concrete (NC) column (control). The seismic performance indexes such as hysteretic response, stiffness and strength degradation, energy dissipation capacity, and ductility were systematically evaluated. Results demonstrated that sleeve‐grouted connections enhanced the integrity and energy dissipation of precast columns, while FRC improved cyclic performance compared to NC due to its superior ultimate strain and crack‐width control capability. A nonlinear finite element model validated by experimental data was employed for parametric analysis, quantifying the correlation between the casting height of precast FRC concrete and seismic behavior. This research demonstrates the reliability of the precast assembly and RCP combination, providing a sustainable solution for precast components. [ABSTRACT FROM AUTHOR]
