This experimental study presents concrete-filled double-skin tubular columns and demonstrates their expected advantages. These columns consist of an outer steel tube, an inner steel tube, and concrete sandwiched between two tubes. The influence of the outer-to-inner tube dimension ratio, outer tube to thickness ratio, and type of inner tube material (steel, PVC pipe) on the ultimate axial capacity of concrete-filled double-skin tubular columns is studied. It is found that the yield strength of the inner tube does not significantly affect the ultimate axial capacity of concrete-filled double-skin tubular composites. With the replacement of the inner tube of steel with a PVC pipe, on average, less than 10% strength is reduced, irrespective of size and dimensions of the steel tube. Hence, the cost of a project can be reduced by replacing inner steel tubes with a PVC pipes. Finally, the experimental results are compared with the existing design methods presented in AISC 360-16 (2016), GB51367 (2019), and EC4 (2004). It is found from the comparison that GB51367 (2019) gives better results, followed by AISC (2016) and EC4 (2004).

In Fire

Composite sections are much of the time used in structures on account of the straightforwardness and speed of erection, and prevalent in fire situation. In concrete consumed chambers the unfilled space is either filled by plain concrete or fortified concrete. In order to decrease the dead weight of composite portions and to assemble the detainment and toughness of the Concrete In-Filled Double Skinned Steel Tubular (CFDST) fragments were grasped. Two reference models, for instance, Concrete Filled Steel Tube (CFST) and Concrete In-Filled Double Skin Steel Tubes (CFDST) were endorsed and were used as references for the parametric examination. The game plan of furrowed steel plates is to improve the bond quality between the strong and the steel tubes and to manufacture the store passing on cutoff of the fragment. The parameters considered in the examination consolidated the strong assessment, thickness of the steel plate and steel grade. The composite structure under scrutiny was impersonated with a tri dimensional numerical model using the ANSYS programming, which relies upon the Finite Element Method (FEM). Examination were done reliant on the center point compressive weight. Examination of the results provoked the assurance that changing a single parameter didn't assemble as far as possible considering the way that the failure was moved to other essential parts in the composite sectionThe decisive results got from the examination of composite portion are improvement or abatement breaking point of fragment that influences the nature of the area in view of changes in the material properties. Sort of composite fragment is included to consider for feasibly picked as building structure. Finally, the stack passing on cutoff of the wrinkled composite sections are higher than the sustained fragment

In this paper, the behavior of concrete-filled double skin steel tubes (CFDST) with simply supported boundary condition was analyzed by Finite Element Analysis method. The Finite Element analysis mode was established and the results have a good consistent with experimental results. The work mechanic and full range analysis of concrete filled double steel tube under lateral impact were analyzed, the results show that the damage of CFDST with simply supported boundary condition under lateral impact is in ductile manner.
