Therefore, recycling and reuse of concrete extracted from demolished reinforced concrete (RC) structure may reduce the usage of natural coarse aggregates (NCA). However, literature review revealed that very few studies had been carried out on seismic performance evaluation of important structural elements like beam-column connections made using recycled coarse aggregates (RCA). In this paper, performance of external RC beam-column connections, made by partially replacing NCA with RCA (25% by weight), has been studied. The beam-column connections have been subjected to low (0.025 Hz: Type-I loading) and high frequency (1 Hz: Type-II loading) cyclic displacement histories. Each of the displacement amplitudes have been increased after completion of three cycles. The various seismic parameters like energy dissipation capacity and stiffness degradation of beam-column connections made using NCA and RCA have been evaluated and compared. The force-displacement hysteresis loops of the beam-column connections made with both NCA and RCA obtained during the experimental investigation were analysed. Comparison of seismic parameters for both categories of specimens established that the beamcolumn connections made with RCA is suitable in case of low to moderate seismic demand.
