Abstract This research introduces a steel-concrete composite wall, namely the concrete-filled double-skin shallow-corrugated steel plate composite wall (CDSCW). It is composed of one concrete-filled double-skin shallow-corrugated steel plate wall (CDSW) and rectangular concrete-filled steel tubular (CFST) columns arranged on the sides of the wall, where the shallow-corrugated steel plates in the CDSW are featured with low energy consumption in production. Full-scale tests are conducted on the compressive behaviour of CDSCWs. Numerical models are also established for further investigation. Based on the extensive parametric study, formulas for the resistance of cross-section to compression, equivalent slenderness ratio, stability coefficient, as well as the resistance of composite wall in axial compression are proposed. It verifies that the proposed formulas are safe and reliable for the resistance prediction of CDSCWs.
Highlights Full-scale tests were conducted for CDSCWs under axial compression. Numerical analysis was performed for CDSCWs. Compressive resistance prediction methods were proposed for CDSCWs.
