“…Based on Eqs. (2) and (3), the load-capacity, experimental and numerical results are compared in Table 3. Compared with the results from the experiment, the average ratio is 0.962 with the mean square deviation of 0.037; while compared with the results from the numerical simulation, the average ratio is 1.065 with the mean square deviation of 0.026.…”

Based on some conclusions of two kinds of concrete-filled double skin steel tube (CFDSST) members with circular or square sections, a new kind of CFDSST with octagonal section, where the outer tube has an octagonal section and the inner tube has a circular section, is proposed in this paper. Behaviors of the CFDSST members with octagon section subjected to axial compression are investigated, and some curves of load-strain of steel tubes and confined concrete and the bearing capacity of members are obtained. It is indicated that the bearing capacity of the columns with octagonal section is larger than that with square section and is smaller than that with circular section, and the bearing capacity of members is related to the ratio of the straight side to the bevelled one. Based on the proper stress-strain relationship, a couple of numerical analyses are made using the finite element software named ANSYS. Finally, a simplified formula is proposed in the paper, and the numerical results agree well with the experimental results and the mathematical solutions. The results are valuable for engineers.

“…A number of experimental investigations showed that, for CFDSTs under axial compression, the passive confining pressure induced by steel tubes can effectively enhance the overall axial capacity by up to 30%; also, its failure mode was reported to be primarily decided by the ratio between the steel tube thickness and cross-sectional diameter (Wei et al, 1995, Zhao et al, 2010b. Furthermore, efforts were also put into studying the behaviours of CFDSTs under transverse loading (Han et al, 2006), tensile loading (Li et al, 2014), torsional loading (Huang et al, 2013) as well as fire (Lu et al, 2010), and they all have evidenced that CFDSTs are able to yield excellent performance under a variety of loading conditions.…”

During the past decades, the use of concrete filled double skin steel tube (CFDST) members has gained much attention in the construction industry due to its beneficial properties such as light weight, high strength and excellent ductility. Many studies have discussed the behaviour of normal strength concrete filled CFDST member under a variety of load conditions; however, the knowledge of UHPC filled CFDST member is relatively lacking. This paper presents a numerical study on the ultra-high performance concrete filled double-skin tubes subjected to blast loading. Numerical models were developed in LS-DYNA and then validated against recently obtained experimental data.
