摘要： 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. In addition, the replaceable components with different energy-dissipation mechanisms facilitate the shear wall structure to have multiple seismic fortification lines, and improve the seismic performance of the building structure.
