Prefabricated Panel House Frame

Prefabricated panel houses generally do not adopt a frame structure but are mainly constructed with brick-and-concrete structures. However, there is a similar concept of modular prefabricated houses that are fundamentally different from frame structures. The following analysis is conducted from the perspectives of structural characteristics, application scenarios, and technical challenges:

Typical Structure of Prefabricated Panel Houses: Brick-and-Concrete with Prefabricated Floor Slabs

Traditional prefabricated panel houses mostly use a brick-and-concrete structure, with walls serving as the primary load-bearing components. Walls are typically constructed using materials such as fired bricks or concrete bricks, bearing both vertical and horizontal loads. Floor slabs are made of prefabricated concrete panels, which are lifted and connected to the walls on-site to form an integrated structure. The advantages of this structure include easy access to materials and mature construction techniques. However, it has relatively low overall stiffness, weak seismic performance, and limited spatial layout flexibility due to wall constraints. For example, in multi-story residential buildings, prefabricated panel houses with brick-and-concrete structures require measures such as the installation of structural columns and ring beams to enhance overall integrity, but they still struggle to meet the needs of high-rise buildings or complex spaces.

Core Characteristics of Frame Structures: Beam-Column Load-Bearing with Non-Load-Bearing Walls

Frame buildings use columns, beams, and floor slabs to form the load-bearing system, with walls serving only as enclosures or partitions and not participating in structural load-bearing. The load-bearing structure forms a spatial frame through reinforced concrete or steel structures, offering the following advantages:

• High spatial flexibility: Walls can be freely arranged to accommodate large-span, multi-functional space requirements;
• Lightweight: Compared to brick-and-concrete structures, frame structures use fewer materials, reducing the foundation load;
• Strong seismic resistance: Frame structures form a ductile system through beam-column joints, effectively dissipating seismic energy. However, frame structures also present technical challenges, such as high consumption of steel and cement, complex construction techniques (requiring formwork support, steel bar tying, etc.), and extremely high requirements for joint connection quality. They are typically used in multi-story and high-rise buildings, industrial plants, or earthquake-prone areas.

Modular Prefabricated Houses: Similar Concept but Fundamentally Different

It is essential to distinguish between "prefabricated panel houses" and "modular prefabricated houses." The latter are factory-prefabricated independent modules (including architecture, structure, electromechanical systems, and decoration) that are assembled on-site, offering advantages such as short construction periods and energy efficiency. However, the load-bearing system of modular houses may still adopt frame structures (such as light steel frames) or lightweight structures (such as timber structures). The core of modular houses lies in "modular production + on-site assembly," rather than the "prefabricated floor slabs + brick-and-concrete load-bearing" approach of traditional prefabricated panel houses. Therefore, modular prefabricated houses and frame structures have some overlap, but traditional prefabricated panel houses have no direct connection to frame structures.

Conclusion: No General Association Between Prefabricated Panel Houses and Frame Structures

There is currently no evidence to suggest that prefabricated panel houses generally adopt frame structures. Traditional prefabricated panel houses are primarily constructed with brick-and-concrete structures, while frame structures are more commonly used in buildings with higher requirements for space and seismic resistance. Although modular prefabricated houses use prefabrication techniques, their structural systems must be selected based on design requirements and have no inherent connection to frame structures.
