View PDF View article View in Scopus Google Scholar The strength and ductility of thin-walled steel columns under cyclic loads are considerably upgraded by filling concrete into hollow spaces surrounded by steel tube and diaphragms. . Hysteresis Model of Thin Infill Plate for Cyclic Nonlinear Analysis of Steel Plate Shear Walls . “Cyclic test of concrete filled steel box columns.” J . Fiber addition enhances the composite action between the steel tube and concrete core, increasing the strength of the concrete core. To better understand how fiber-reinforced infilled steel–concrete composite thin-walled columns (SCTWCs) behave, multiple investigations have been conducted using both experimental and analytical methods. This article provides a .
Steel sections with concrete infill are being increasingly used as structural members, since filling the steel section with concrete results in an increase in both strength and ductility without increasing the section size. In this paper, the results of 11 cantilever thin-walled steel box column specimens tested under constant compressive. Expand Buckling modes of steel sections with concrete infill: (a) box section (CFST column); (b) I section (PEC column); (c) I section with links (strengthened PEC column). .
