Abstract: The present disclosure relates to an assembled shear wall, specifically a wall corner component with self-centering energy dissipation, including an upper connector, a middle connector, a lower connector and a foamed aluminum block. The upper connector is connected to the middle connector through an energy dissipation steel bar, and the middle connector is connected to the lower connector through a shape memory alloy bar. The bottom of the foamed aluminum block is offset from the bottom of the lower connector, and the top of the foamed aluminum block runs through a first limit hole and offsets the lower side of the middle connector. The wall corner components provided by the present disclosure have both energy dissipation capacity and self-centering ability, which is helpful to realize the rapid recovery of the post-earthquake use function of the shear wall.

Abstract: A novel function-recoverable prefabricated seismic shear wall structure with replaceable components, which includes main structural components, connecting components and replaceable components. All components are connected by bolts or pins. The connections can provide sufficient strength to effectively connect adjacent upper and lower wall panels, or wall panel and coupling beam, together. The replaceable components are installed in the bottom region of the wall and coupling beams, which provide sufficient bearing capacity and stiffness for the building structure under service loads and dissipate seismic energy under the earthquake. The damage concentrates on the replaceable components which could be easily replaced after a strong earthquake so that the function of the building structure could be quickly restored.
