Experimental Research on Seismic Behaviour of the Concrete-Filled Double-Steel-Plate Composite Wall

Abstract

The concrete-filled double-steel-plate composite wall is a new type of structural member that is widely used in super high-rise buildings. To study the seismic behaviour of such wall, nine specimens are tested under axial compressive force and reversed cyclic horizontal load. This paper presents the mechanical behaviour of the wall specimens and their components, including stiffness, failure mode, seismic performance and ultimate load-bearing capacity. The influences of the height-width ratio, the plate thickness, the concrete strength and the axial compression ratio on the seismic performance of such wall are also investigated. The test results reveal that the concrete-filled double-steel-plate composite wall makes full use of steel and concrete. The concrete-filled double-steel-plate composite wall is a new type of structural member with better lateral resistance.
