Tests on Seismic Behaviors of Double Thin Skin Hybrid Walls Filled with Demolished Concrete Lumps

Abstract:

Double thin skin hybrid walls filled with demolished concrete lumps (DCLs) are composed of two steel plate skin connected by rib plates, with the space between them filled with new concrete and demolished concrete lumps. In order to investigate the seismic behavior of double thin skin hybrid walls filled with DCLs, quasi-static tests of seven specimens were conducted. The parameters considered in the tests are: replacement ratio of DCLs, thickness of steel plate, axial load ratio, rib plate spacing and height-width ratio. Test results show that the seismic performances of double thin skin hybrid walls filled with DCLs are similar to the walls without DCLs, and the double thin skin hybrid walls filled with DCLs also exhibit acceptable ductility and energy dissipation ability.
