Abstract

This paper presents an experimental investigation of axially loaded concrete-filled cold-formed steel elliptical sections. Currently, limited test data are available on concrete-filled cold-formed steel elliptical stub columns. In this study, a total of 13 concrete-filled stub column tests was conducted on cold-formed steel elliptical sections. The nominal aspect ratio of the elliptical sections ranged from 1.65 to 2.77. Tensile coupon tests and concrete cylinder tests were conducted to obtain the material properties of the steel and concrete, respectively. The nominal infilled concrete strength ranged from 40 to 100 MPa. The test strengths obtained from this study were compared with the nominal strengths calculated from the European Code and American Specification. The column strengths predicted by these specifications are conservative.
