Performance of Prefabricated Houses in Typhoons

The performance of prefabricated houses in typhoons depends on various factors, including their design, construction quality, and typhoon intensity. Under the influence of a mild typhoon, if a prefabricated house is reasonably designed and reliably constructed, it can generally maintain structural stability without significant damage. However, when faced with strong or even super typhoons, prefabricated houses may encounter significant challenges. Strong winds can cause damage to the building envelope (such as exterior wall panels and roof panels), leading to loosening or detachment. If the connection joints of the house are not sufficiently robust, it may also result in overall structural deformation or even collapse.

Key Points for Typhoon-Resistant Design of Prefabricated Houses

• Structural Selection: Choose a structural form with good wind resistance, such as a frame structure. A frame structure can effectively resist horizontal forces and bending moments generated by wind loads through the coordinated work of beams, columns, and other components, improving the overall stability of the house.
• Connection Design: The connection between prefabricated components is a crucial aspect. Adopt reliable connection methods, such as bolt connections and welding, to ensure that the connection joints have sufficient strength and stiffness. At the same time, necessary shear keys and tension anchors should be installed to enhance the connection reliability between components and prevent connection failure under typhoon conditions.
• Building Envelope: The building envelope should possess a certain level of wind pressure resistance. Exterior wall panels and roof panels should be made of materials with high strength and good toughness and installed in a reasonable manner to ensure a firm connection with the main structure. Additionally, an appropriate drainage system should be installed to prevent rainwater accumulation from causing damage to the building envelope during typhoons.
• Foundation Design: A stable foundation is an important guarantee for the typhoon resistance of prefabricated houses. The foundation should have sufficient bearing capacity to transfer the wind loads acting on the house to the ground. At the same time, the foundation form should be reasonably selected according to local geological conditions and typhoon characteristics, such as independent foundations or raft foundations.
