Cement Prefabricated House and Typhoon
Cement prefabricated houses perform well in resisting typhoons and can generally withstand typhoons of around force 12. The following provides an explanation from three aspects: design, actual measurements, and influencing factors:
From the design perspective, well-made cement prefabricated houses take full account of extreme weather conditions, especially the impacts of strong winds and heavy rain, during the design process. For example, assembled cement houses adopt a robust "full-frame shear wall" design. This structure can effectively disperse the impact of wind forces on the house, enhancing overall stability. Under the test of a force-12 typhoon (with a wind speed of 32.7-36.9 m/s), the modules are connected by prestressed bolts, ensuring the firmness of the connections without any loosening. Meanwhile, the design of the roof waterproofing membrane also fully considers wind pressure factors, reducing the risk of being blown off and thus safeguarding the house's waterproofing performance.
From the perspective of actual measurements, the typhoon resistance capability of cement prefabricated houses has been practically verified. Taking the typhoon measurements in Yangjiang, Guangdong as an example, the prefabricated cement house demonstrated excellent wind resistance performance under the侵袭 (invasion, here it means 'impact' would be more appropriate in English, so we use 'impact' in the following translation) of a force-12 typhoon. In contrast, the adjacent traditional brick houses had tiles flying off in the typhoon, while the exterior wall tiles of the prefabricated cement house did not fall off, and the deformation of the doors and windows was less than 1 mm, fully proving its structural safety and stability under extreme weather conditions.
From the perspective of influencing factors, although cement prefabricated houses have significant advantages in resisting typhoons, their wind resistance capability is not solely determined by the house itself. Factors such as the geographical location of the house, the surrounding environment, and the stability of the foundation also affect its wind resistance performance. For example, houses located in open areas or on hilltops may face stronger wind impacts; while an unstable foundation may cause the house to tilt or collapse in a typhoon. Therefore, when constructing cement prefabricated houses, it is necessary to comprehensively consider these factors and take corresponding reinforcement measures to ensure the safety of the house under extreme weather conditions such as typhoons.
