Prefabricated Hybrid House Structure

"Prefabricated Hybrid House Structure" is not a standard term. Related concepts include prefabricated houses (prefabricated assembled buildings) and hybrid structural buildings. Here is a detailed introduction:

Prefabricated Houses (Prefabricated Assembled Buildings)

Prefabricated houses, also known as prefabricated assembled buildings, refer to a form of construction where building components are industrially produced and assembled on-site.

• Technology and Components: This encompasses prefabricated concrete structures and steel structures, with components including prefabricated products such as beams, slabs, walls, and columns.
• Advantages: They offer significant advantages such as shortened construction periods and reduced pollution. For example, a real estate project in Shanghai adopted modular construction (a more integrated form of prefabricated assembled building), reducing the construction period by more than 60% compared to traditional buildings. A public housing project in Shenzhen, Guangdong, assembled from 6,028 concrete modules, reduced the completion and delivery period from 2.5 to 3 years to just 1 year.
• Development History: China's prefabricated concrete technology began in the 1950s, initially applied in factory and residential construction. In the 1970s, driven by the policy of "industrialization, standardization, and mechanization" in construction, technical systems such as large-panel structures and box structures emerged. By the mid-1980s, the technology stagnated due to cost and quality issues. However, in the 21st century, it has revived due to production efficiency and environmental advantages. Companies like Vanke Group have developed prefabricated shear wall residential structural systems and applied prefabricated frame technology in engineering projects.
• Application Cases: The Nanjing Jindi Yufang project adopted a prestressed prefabricated concrete assembled integral frame structural system. Regions like Fujian Province have established industrial bases with policy support, achieving a reduction in construction waste by more than 70%. Chinese-made prefabricated houses are also popular overseas. According to customs data, in the first four months of 2026, the Guangzhou Customs district exported movable houses worth 1.4 billion yuan, a year-on-year increase of 38.1%.

Hybrid Structural Buildings

These refer to buildings that use multiple building materials as primary load-bearing components or employ two or more building structural systems within the same building. By combining the mechanical properties of different materials, a composite load-bearing system is formed to optimize the overall performance of the building.

• Common Combinations: Vertical load-bearing components often use brick walls, brick columns, or reinforced concrete columns. Horizontal components are paired with reinforced concrete floors, large beams, or steel-wood roof trusses. The foundation commonly uses materials such as lime soil, bricks, rubble, or concrete.
• Advantages: They can combine the advantages of different materials to optimize the overall performance of the building. For example, a T-shaped or inverted T-shaped composite beam structure is firmly constructed by combining tension wood with primary compression wood using adhesives, supplemented by short-length wood as additional compression components. This reduces wood demand, lowers costs, and allows for wider beam spacing.
