摘要
This paper is an attempt to study the performance of concrete filled steel tubular (CFST) members with square sections under both loading and chloride corrosion. A total of 28 specimens, including 17 stub columns and 11 beams, were tested. The main parameters were loading ratio (from 0 to 0.75) during corrosion, as well as corrosion condition (no corrosion, and fully or half immersed into corrosive solution, respectively). According to the test, the effects of both loading and corrosion on the behaviour of CFST and reference hollow steel tubular members were analyzed. Comparisons between the predicted ultimate strength by using the existing codes of DBJ/T13-51-2010 and EC4-2004 and the testing results were proposed. (C) 2011 Published by Elsevier Ltd.
