The mechanical behavior of dove tail profiled steel concrete composite shear walls under axial compression

Abstract

This paper presents an experiment on the dove tail profiled steel concrete composite shear wall (DSCW) under axial compression. Four DSCWs specimens were designed and constructed in order to test and obtain the deformation behavior, failure modes, bearing capacity, stiffness changes, etc. The results indicate that the failure process of all 4 specimens is initialed from steel sheets local buckling to the final concrete crushing. The steel and concrete can work consistently because the dove-tail-shaped ribs of the sheets have a good anchoring effect on the concrete. Based on the experiment result and analysis, a simplified formula for DSCWs was suggested to calculate the axial compressive strength with consideration of the influence of local buckling of steel sheets.This paper presents an experiment on the dove tail profiled steel concrete composite shear wall (DSCW) under axial compression.
