摘要

This paper is an attempt to study the cyclic performances of recycled aggregate concrete (RAC)-filled steel tubular columns. Thirteen specimens with circular section, including 10 RAC-filled steel tubular (RACFST) columns and 3 reference normal concrete-filled steel tubular (CFST) columns, were tested under constant axial load and cyclically increasing flexural loadings. The parameters in the test are: (1) concrete type: normal concrete and recycled aggregate concrete; and (2) axial load ratio (n), from 0.05 to 0.52. It was found that, generally, the performances of RACFST columns under constant axial load and cyclically increasing flexural loadings are similar to the corresponding normal CFST columns, and RACFST columns can also exhibit high ductility levels and energy dissipation abilities.
