An innovative composite wall, namely corrugated double-skin recycled aggregate concrete composite (Co-DR) wall, consisting of recycled aggregate concrete (RAC) filled steel tubes, two exterior steel faceplates connected by tie bolts with RAC infill, was proposed in this paper. Three double-skin composite wall specimens with different type of infilled concrete and faceplate profile were tested under combined axial and cyclic lateral loads. Failure mode, cyclic behavior, strength properties, deformation and energy dissipation capacities of the specimens were presented. Test results indicated that all specimens presented compression-flexure failure and showed expected seismic performance. Using RAC as infilled concrete decreased lateral strength and ductility of the double-skin composite wall slightly, while using corrugated plates as faceplates contributed to improve lateral strength, ductility, and energy dissipation capacity of the double-skin composite wall significantly. Comparing with the double-skin composite wall with flat faceplates and normal concrete, the double-skin composite wall with corrugated faceplates and recycled concrete presented competitive seismic performance, with a lateral strength increased by 10.92%, a ductility ratio decreased by 5.23%, and a cumulative energy dissipation increased by 16.51%. It is acceptable to use the double-skin composite wall with RAC as infilled concrete and corrugated plates as exterior faceplates as lateral load resisting system for mid- to high-rise buildings in seismic zones.
