Analysis of ultimate bearing of concrete filled<br /> double skin steel tubular columns<br /> <br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 9
Abstract
Based on the Twin Shear Unified Strength Theory, the unified calculation formula of bearing capacity of concrete filled double skin steel tubular members subjected to axial compressive loading is derived. A comparison between the theoretical result and the experimental data in the literature is achieved. The results show that the Twin Shear Unified Strength Theory is versatile in the theoretical analyses of concrete filled double skin steel tube. The reliable theoretical foundation can be provided for the optimum design of concrete filled double skin steel tube. Key words: structure engineering；the reciprocity force；the ultimate load；Unified Strength Theory；concrete filled double skin steel tube
