Conventional buildings use beambrace members to dissipate seismic energy. However, these members may cause residual deformation of buildings under large earthquakes, which affects the building seismic performanceincreases the difficulty of reuse after earthquakes. Therefore, a novel earthquake-resisting member "Dual-Core Self-Centering Brace, DC-SCB” was developed. The DC-SCB uses tendons to provide the elastic restoring forcea friction devicesteel bars to provide energy dissipation so that the building can return to the original position after major earthquakes. The DC-SCB significantly reduces the residual deformationrepair cost of the building after earthquakes, also reducing the large lateral displacementcollapse of the building.
