Traditional housing construction technology has low production efficiency, slow construction speed, long construction period, high material consumption and high labor intensity. These series of conditions can no longer meet the rigid demand for housing in modern society. The prefabricated building has the following characteristics: ①The design is diversified and can be designed according to the housing requirements; ②The function is modernized, and a variety of new materials such as energy saving and environmental protection can be used; ③Manufacturing is factory-based, which can make the building components and accessories uniform and factory-made. ; ④ Construction assembly can greatly reduce labor force and reduce material waste; ⑤ Time optimization can significantly speed up the construction cycle. The prefabricated building pays attention to the protection of the environment and resources. During the construction process, it effectively reduces the pollution of construction sewage, harmful gases, dust emissions and construction noise, and reduces the various impacts of construction on the surrounding environment, which is conducive to improving the construction efficiency. Labor productivity promotes the refinement of design and construction, improves the overall quality of buildings and the rate of energy conservation and drainage reduction, promotes the healthy and sustainable development of my country's construction industry, and meets the needs of national economic development.

Prefabricated buildings are mainly divided into prefabricated concrete structures and prefabricated steel structures.

However, because the assembly quality of vertical components is not easy to guarantee, the integrity is relatively Poor pouring structure, transportation and installation are prone to problems and other current constraints, and the promotion and application are limited to a certain extent. The prefabricated steel structure has a high assembly rate, energy saving and environmental protection. However, in view of the impact of cost and cost, most high-rise residential buildings in my country currently use reinforced concrete shear wall structures, and corrosion and fire prevention also restrict the promotion of steel structure residential buildings.

If the steel structure and the concrete structure are effectively combined, a new type of assembled lateral force-resistant member is studied, and the respective advantages of the concrete and steel structures are fully utilized, which is a good solution to the shortcomings of the current structural system.
