Elastic Analysis on Post-Local Buckling of Steel Plates in Thin-Walled Rectangular Concrete-Filled Steel Tube Columns

Article Preview

Abstract:

With the wide application of high-strength concrete and thin-wall steel tube in concrete-filled steel tube, it is essential to study the post-local buckling behavior of rectangle steel plates. Based on large deflection theory of plate, the post-local buckling behavior of steel plates in concrete-filled steel tube is analyzed in this paper. At the same time, the post-local stress of steel plates is obtained. The results indicate that the post-local buckling behavior of steel plates can be effectively utilized in large width-to-thickness ratios of steel plates.
