The traditional concrete structure requires a lot of manual work on site, and there are many wood applications in the construction. The pollution of wastewater and dust is serious, which does not meet the national energy conservation and environmental protection policy requirements. However, the shear wall structure system in the concrete structure provides a good anti-side stiffness while the building layout is flexible. Especially in the residential structure, the shear wall is thinner and can be combined with the building partition wall to provide a comfortable interior space.

Steel structure is an industrialized building system that meets the requirements of building industrialization standards for standardized design, factory production, assembly construction, and information management. The on-site assembly construction section is about a lot of labor, and the construction waste is small, energy saving and environmental protection. The steel column, steel beam, support and other components in the steel structure system still occupy a considerable proportion in manual production, and the node domain structure is complicated and the production cost is high. Most of the steel columns are square rectangular columns. When used in residential buildings, there are steel column lobes in the room, which brings inconvenience to the building layout.

If the steel structure and the concrete structure are effectively combined, a new type of anti-side force member is studied, and the concrete layout of the concrete shear wall is flexibly utilized, the degree of industrialization of the steel structure is high, and the construction speed is fast, and the steel is light.
