Abstract

Recycled aggregate concrete (RAC) is a kind of new material which utilizes the waste concrete with the significant advantages of environmental protection and economic benefit. Its members have inferior structural performances compared with normal concrete members. However, their performance may be enhanced if they are confined by steel tubes. In this paper, the experiments on 36 recycled aggregate filled steel columns, including 18 recycled concrete filled steel tubes (RACFST) and 18 recycled concrete filled double skin tubes (RACFDST) subject to compressive axial load are carried out. The failure modes and load deflection relationship are described. Meanwhile, the effect of recycled aggregates (RA) replacement ratio on the behavior of such composite sections is investigated. Comparisons are made with predicted ultimate strengths ofRACFST columns using existing codes. Mechanics models will be developed to predict the capacities of RACFST and RACFDST. © 2011 Taylor & Francis Group, London.
