Abstract

Tests on sixteen concrete filled steel tubes to investigate the influence of concrete compaction methods on the section capacities of concrete filled steel tubes with rectangular sections are reported. The main objectives of these tests were twofold: firstly, to report a series of tests on composite stub columns under different concrete compaction methods; and secondly, to investigate the influence of concrete compaction on the section capacities and the modulus of elastic of concrete filled steel tubes with rectangular sections. It was found that better compaction of concrete resulted in higher section capacities and higher elastic moduli in concrete filled steel tubes. The tests showed the importance of good concrete compaction for concrete filled steel tubes with rectangular sections.
