In the face of the acceleration of the life footsteps, the continuous improvement of the labor cost becomes a problem for reducing the expenditure of the labor cost under the condition of improving the efficiency. For the construction industry, the construction materials are also developed towards prefabrication and assembly. The prefabricated building is a building which is prefabricated in a factory to construct all components required by a certain building, transports the assembled components to a construction site, and splices the components in the construction site in a hoisting mode through a crane. The prefabricated building has the advantages of convenient transportation, high construction speed, low requirement on environment and the like because the components are prefabricated in factories and produced in a standardized manner, and is widely applied abroad. At present, the method is also a great direction for the development of the domestic building industry.
The steel has the advantages of high strength and good ductility, and a structural system taking the steel as a building material is always considered to be an ideal anti-seismic system. The steel plate shear wall begins to appear abroad as early as the seventies of the last century, and the shear wall consists of an edge restraining member and an embedded steel plate. The embedded steel plate shear wall is adopted to replace the traditional concrete shear wall, and is taken as a new technology which is used in some new projects in high-intensity earthquake fortification areas of China in recent years.
The traditional embedded steel plate shear wall is divided into a thick steel plate shear wall and a thin steel plate shear wall according to the thickness of an embedded steel plate. The thick plate shear wall has larger in-plane rigidity, ductility and stable hysteretic performance due to larger thickness of the steel plate, and is not easy to generate local buckling under the action of lateral horizontal force, but the steel plate wall has high cost and is inconvenient to transport. The sheet shear wall is easy to bend under the action of lateral horizontal force, tension belts are formed in the diagonal direction of the steel plate, and the purpose of energy consumption is achieved through the tension deformation of the tension belts during an earthquake. For the thin plate shear wall, the stress performance can be improved by arranging the stiffening ribs, and the out-of-plane rigidity of the steel plate shear wall can be improved by providing certain out-of-plane constraint.
