“…Liang and Uy [14] investigated the local and post-local buckling behavior of steel plates in concrete-filled steel box columns under axial compression using the finite element method and proposed effective width formulas for the ultimate strength design of steel plates in such columns. Liang et al [15] has incorporated these effective width formulas into their fiber element analysis programs for the advanced analysis of concrete-filled thin-walled steel box columns to account for local buckling effects. Moreover, Liang et al [16,17] proposed buckling and ultimate strength interaction formulas for the design of steel plates in double skin composite panels under biaxial compression and shear.…”

“…The critical buckling stress f bs in elastic and inelastic ranges can be determined by the well-known formula of Eq. (5) (Gerard 1946), and the post-local buckling behavior can be described by the effective width approach (von Karman et al 1932;Winter 1947;Shanmugam et al 1989;Usami 1993;Bambach and Rasmussen 2004a, b;Bambach and Rasmussen 2004;Liang et al 2006;Mazzolani et al 2011). In the effective width approach, the stress redistribution within a buckled steel plate is simplified by assuming that only a certain width of the plate remains effective.…”

To investigate the load-carrying capacity of high-strength concrete-encased steel angle (CES-A) columns, in which corner steel angles are encased in concrete and transmit column loads directly, a numerical study was performed by using a proposed analysis model. The proposed model considered the strain compatibility, confinement effect, local buckling, and premature cover-spalling, and was verified against previous experimental study results. To investigate the effect of design parameters, a parametric study was conducted, and based on the parametric study results, a simple approach was also discussed to predict the residual strength (2nd peak load) after spalling of concrete cover at corners (1st peak load). The numerical investigations showed that when steel contribution and confinement efficiency are high, CES-A columns exhibit relatively large load-carrying capacity even after cover-spalling, due to the maintained strength of confined concrete and yielding of steel angles, and the proposed simple approach gave a good prediction for the residual strength.

“…On the basis of the theory in Han [3] and Zhong [4], some new materials are used and analyzed in the papers. Liang et al [5] ~ [7] investigated the strengths and behavior of short concrete filled thin-walled steel box columns with local buckling effects by nonlinear fiber element analysis, with the study of several essential effects on the stiffness, strength and ductility of high strength thin-walled CFST beam columns under combined axial load and biaxial bending, and studied the critical local and post-local buckling behavior of steel plates in concrete-filled thin-walled steel tubular beam-columns. Mohanad and Uy [8] ~ [9] presented the experimental and theoretical studies of the behavior of hollow and concrete filled steel columns fabricated with high strength structural steel plate and subjected to biaxial bending.…”

ABSTRACT:The concrete-filled square steel tubular structure has been applied wildly in the practical projects around the world. To install CFRP into the column is beneficial not only to overcome the disadvantages of the high-strength concrete, but also to improve the bearing capacity and the stability of the concrete-filled square steel tube. This paper adopts finite element analysis software ABAQUS 6.7 to make nonlinear finite element analysis on a large number of long columns of high-strength concrete-filled square steel tube with inner CFRP circular tube subjected to axial compression. The analysis results are verified by the tests. In addition, the load-axial strain curves in the whole process are calculated and analyzed, and they are divided into 4 segments: elastic phase, plastic phase, descending phase and rebound phase. Based on the curves of load-axial strain, the stresses analysis on the core concrete, CFRP tube and square steel tube are conducted. The results of finite element simulation analysis show the destruction of long columns subjected to axial compression are all buckling failure. It indicates that slenderness ratios are the key to decide the type of buckling failure for long columns under axial compressive loading. The boundary slenderness ratio between elastic buckling and plastic buckling is discussed.
