Behaviors of recycled aggregate concrete-filled steel tubular columns under eccentric loadings

Vivian W. Y. TAM, Jianzhuang XIAO, Sheng LIU, Zixuan CHEN

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 3,   Pages 628-639 doi: 10.1007/s11709-018-0501-7

Abstract: The paper investigates the behaviors of recycled aggregate concrete-filled steel tubular (RACFST) columnsA total of 16 RACFST columns were tested in this study.Experimental results showed that the ultimate stresses of RACFST columns decreased with increasing recycledreduce the decrement; the incorporation of expansive agent decreased the ultimate stresses of RACFST columnsand has more effect than that of the normal aggregate concrete-filled steel tubular columns.
