What to Do with Prefabricated Houses in Strong Winds

Prefabricated houses can ensure safety in strong winds through pre-event preparations, enhancing the wind resistance of the houses themselves, regular maintenance and inspections, and responses to special weather conditions.

Pre-event Preparations

It is crucial to establish a comprehensive meteorological monitoring and early warning system. Construction sites should be equipped with professional meteorological monitoring equipment to monitor parameters such as wind speed and direction in real time, and maintain close contact with local meteorological departments to obtain accurate weather forecasts. When the wind speed reaches or exceeds the critical wind speed allowed for construction (usually Level 5, i.e., 8.0 - 10.7 m/s), an early warning for strong winds should be issued immediately to enable timely response measures. Meanwhile, construction plans should be optimized, taking full account of the impact of strong winds and formulating targeted construction measures. For areas with frequent strong winds, component installation plans should be optimized to ensure the safety and stability of the construction process.

Wind Resistance Measures for the Houses Themselves

• Structural Design and Material Selection: Use high-strength, durable building materials such as reinforced concrete, and carry out reasonable structural design, including rational beam-column layouts and reinforcement of node connections, to improve the overall stiffness and stability of the houses. Structural reinforcement can also be achieved through methods such as prestressing technology or external steel bonding to enhance the wind resistance of the houses.
• Optimization of Building Form and Fixing Methods: The building's exterior should be as regular as possible to reduce the wind concentration effect caused by edges and corners, and minimize gaps to reduce wind penetration. The building should be firmly fixed to the ground using methods such as ground anchors to prevent displacement or overturning during strong winds. Additionally, consider setting up ventilation openings to balance the internal and external air pressure differences and reduce wind pressure on the houses.

Regular Maintenance and Inspections

During daily use, regularly inspect and maintain the integrity of the houses, promptly identify and address potential safety hazards, such as crack repairs. Meanwhile, regularly evaluate and test the load-bearing capacity of the houses to ensure they always operate within a safe and controllable range.

Responses to Special Weather Conditions such as Typhoons

Evaluate the safety of the houses in advance to determine whether they can withstand typhoon attacks. If there are safety hazards in the houses, reinforcement measures should be taken promptly to improve their structural stability and wind load capacity. Before the arrival of a typhoon, if the houses cannot guarantee living safety, evacuate to a safe area in a timely manner to ensure life safety.
