This　paper　investigates　the　seismic　behavior　of　concrete　members　incorporating　recycled　coarse　aggregates.　Tests　were　carried　out　on　three　full-scale　specimens　with　a　600　mm　side　length.　The　main　parameters　include　axial　load　ratio　(ALR)　and　the　employment　of　CFRP　external　confinement　and　spiraled　groove　ultra-high-strength　steel　bars　(UHSSBs)　with　a　nominal　yield　strength　of　1400　MPa.　Lateral　cyclic　displacement　and　co-existing　axial　load　were　applied　to　specimens.　After　describing　the　experiment　results　and　observations,　an　iterative　method　was　proposed　to　investigate　the　relationship　between　reinforcement　slip　and　reinforcement　stress.　Based　on　the　iterative　method,　the　lateral　capacity　and　displacement　of　members　reinforced　with　UHSSBs　were　discussed.　The　recycled　coarse　aggregate　concrete　columns　employed　both　the　CFRP　jacket　and　the　UHSSBs　can　maintain　positive　lateral　stiffness　under　a　4%　drift　and　have　less　residual　drifts　compared　with　that　of　the　traditional　ductile　column.　Besides,　the　increase　of　ALR　gives　rise　to　higher　residual　drift.　The　method　proposed　here　is　capable　of　predicting　the　experimental　yield　loading　capacity　and　the　yield　drift.
