Behaviors of recycled self-compacting concrete filled steel tubular (RSCCFST) columns under eccentric compression were experimentally investigated in this paper. The influences of the recycled coarse aggregate (RCA) replacement ratios, length-diameter ratios, eccentricities, and concrete strength were examined. According to the tests, the RSCCFST columns demonstrated a satisfying performance under the eccentric loads. The failure modes of short and long RSCCFST columns are drum-like bending and flexural buckling, respectively. Large replacement ratio of RCA and length-diameter ratio would reduce the member stiffness and increase the yielding and ultimate deflections; while the variation of concrete strength has little effect on the deflections. Therefore, to improve the member bearing capacity, the most effective way is to reduce the RCA replacement ratio, length-diameter ratio and increase the concrete strength. Furthermore, based on the fiber strip method, a numerical analysis approach for conveniently evaluating the load-deflection relationship of the RSCCFST columns was developed. The load-deflection curves of the specimens were calculated with the numerical method and compared with the test data. The verifications illustrated the proposed method has good accuracy and can be adopted in engineering practices.
