Analysis of Seismic Performance of Prefabricated Shear Wall Structures
In order to deeply analyze the seismic performance of prefabricated shear wall structures,the load-displacement curves,stiffness degradation curves,ductility properties and dissipation properties of three kinds of shear wall structures were compared in this paper.The re-sults show that with the increase of loading displacement,the load level of the assembled shear wall increases approximately linearly at first,then decreases rapidly and then slowly.The stiffness degradation curve of the prefabricated shear wall shows an approximate normal distribu-tion.The smaller the section size of the column,the greater the ductility and axial compression ratio,the greater the ductility of the prefabrica-ted shear wall.The larger the column section size,the stronger the yield performance of the prefabricated wall structure specimen,the smaller the axial compression ratio,the stronger the yield performance of the prefabricated wall structure specimen.
