“…On the other hand, for the tangential direction a Coulomb friction elements were used. According to many authors the value of friction coefficient ranges between 0.2 to 0.6 [2,11,12]. For these models the value of 0.47 was used [13].…”

“…Constitutive material models have significant impact on the precision of the results. In the literature many constitutive models are described with smaller or bigger accuracy of concrete and steel behaviour [1,2,3,4,5,6]. Using computer program Abaqus [7] and Riks method which is available in this program critical buckling forces are determined.…”

“…Empirical equations proposed by Hu et al [20] can be utilised to determine the approximate value of k 3 . To consider the effect of different concrete strengths, the reduction factor r was introduced by Ellobody et al [9] on the basis of the experimental study carried out by Giakoumelis and Lam [13]. According to Tomii [44] and also Mursi and Uy [35], the value of r has been adopted as 1.0 for concrete with cube strength f cu equal to 30 MPa and as 0.5 for concrete with f cu greater than or equal to 100 MPa.…”

This paper investigates the behaviour of axially loaded stiffened concrete-filled steel composite (CFSC) stub columns using the finite element software LUSAS. Modelling accuracy is established by comparing results of the nonlinear analysis and the experimental test. The CFSC stub columns are extensively developed using different special arrangements, number, spacing, and diameters of bar stiffeners with various steel wall thicknesses, concrete compressive strengths, and steel yield stresses. Their effects on the columns behaviour are examined. Failure modes of the columns are also illustrated. It is concluded that the parameters have considerable effects on the behaviour of the columns. An equation is proposed based on the obtained results to predict the ultimate load capacity of the columns. Results are compared with predicted values by the design code EC4, suggested equation of other researchers, and proposed equation of this study which is concluded that the proposed equation can give closer predictions than the others.

“…The concrete confinement was achieved by matching the numerical results by trial and error using a parametric study. A multi-linear stress-strain curve for the steel tube was used and the interface between concrete and steel tube was modeled to improve the analytical results of the ABAQUS program (Ellobody et al 2006). The accuracy of these analytical methods has been verified by the results of the tests.…”

In this paper, the predictions of ultimate strength of circular concrete-filled steel tube (CFT) stub columns using current design codes such as AIJ-2001, AISC-2005, DL/T-1999, and Eurocode 4-2004, are examined and compared with published experimental tests of CFT short columns made with normal-and highstrength steel and concrete. Based on the investigations, a simple formula for predicting the ultimate strength of CFT stub columns is proposed. The concrete confinement, which depends mainly on the ratio of the external diameter of the steel tube to the plate thickness, the yield stress of the steel tube, and the unconfined compressive strength of the filled concrete, was reasonably achieved in the proposed formula. From comparisons with the published experimental data for CFT short columns of normal and high strength steel and concrete, the present formula is shown to give a good representation of the ultimate strength of circular CFT columns.
