Axial Compression Performance of Rubberized Concrete-Filled Steel Tube Short Columns

Abstract

Abstract: In order to solve the limitation of engineering application of rubberized concrete caused by its lower strength and elastic modulus, 12 rubberized concrete-filled steel tube (RuCFST) columns, in which waste tire rubber was used to replace fine aggregate by the same volume, were fabricated and tested under axial compression in this paper. The test results show that the steel tube of RuCFST columns is more prone to local buckling and RuCFST columns exhibit lower axial compressive capacity and higher ductility than normal CFST columns. RuCFST columns demonstrate hardening post-peak response, compared with normal CFST columns with the same steel tube thickness. Finally, the axial compressive capacity of RuCFST columns was investigated by AISC 360—2005, Eurocode 4 and GB 50936—2014 codes. The results show that the predictions of the axial compressive capacity of RuCFST columns by AISC 360—2005 and GB 50936—2014 are conservation and Eurocode 4 provides the most accurate results compared with the test results.
