Abstract

Abstract

Based on the quasi-static tests of three wall specimens with different axial compression ratios, the failure modes, bearing capacity, stiffness degradation, energy dissipation capacity, lateral deformation and shear deformation of the double-skin multi-cavity composite wall with steel truss were explored and analyzed in the paper. The results showed that the innovative double-skin composite wall with steel truss had better bearing capacity, ductility and energy dissipation capacity. When the aspect ratio was 2.0, the main failure characteristics of the specimens were local shear buckling of steel plates, fracture and buckling of steel tubes, and compressive crushing of concrete. The shear deformation accounted for 20% to 40% of the overall lateral deformation, and all specimens were damaged in shear-compression mode. The effect of axial compression ratio on the horizontal bearing capacity and stiffness degradation of the specimens was small, and the specimens with small axial compression ratio showed better ductility.
