Xiamen Earthquake-Resistant Container House

The earthquake-resistant container houses in Xiamen possess certain earthquake-resistant capabilities in terms of design and application, but their earthquake-resistant performance needs to be comprehensively evaluated based on specific product standards, renovation processes, and usage scenarios.

1. Structural Design and Earthquake-Resistant Foundations
Some container houses in Xiamen adopt a light steel structural system, with the main frame composed of thickened steel. For example, the products of Xiamen Qing'anju Portable House Co., Ltd. have a steel structural system that can withstand wind speeds of 120 km/h and maintain integrity under a seismic fortification intensity of 9 degrees. This design originates from the original modular structure of containers, with the toughness of steel and the reliability of welding processes providing a foundation for earthquake resistance. For instance, the container house products of Chengdong Camp have been experimentally verified by Tianjin University to withstand an earthquake intensity of 8 degrees (equivalent to a magnitude 6.4 earthquake) and reduce damage through the toughness of the light steel structure.

2. Renovation Processes and Earthquake-Resistant Enhancements
When renovating second-hand containers into houses, earthquake-resistant performance needs to be enhanced through processes. Xiamen Wangshida Portable House Co., Ltd. follows the original container design standards during renovation, repairing welds, applying anti-corrosion coatings on surfaces, and installing internal insulation layers and electrical systems. Some companies also reinforce the structure, such as increasing the cross-sections of beams and columns, reinforcing load-bearing nodes, or adding wind-resistant cables to meet higher earthquake-resistant requirements. For example, in areas with strong winds, container houses enhance the stability of cladding materials by increasing the density of fixed self-tapping screws and adding structural purlins.

3. Application Scenarios and Earthquake-Resistant Adaptability
Container houses in Xiamen are mostly used for construction site offices, temporary dormitories, emergency shelters, and other scenarios that require rapid deployment and basic earthquake resistance. For example, in the house earthquake-resistant reinforcement project promoted by Tong'an District in Xiamen, container houses have been included in the temporary shelter plan due to their modular and relocatable characteristics, and their earthquake-resistant performance needs to comply with the standards of the local "Implementation Plan for House Facility Earthquake-Resistant Reinforcement Projects." Additionally, the lightweight structure of container houses reduces the risk of collapse during earthquakes, providing time for personnel evacuation.

4. Purchase and Usage Recommendations
When selecting, demanders should pay attention to the renovation processes of suppliers, such as steel thickness, weld quality, and anti-corrosion treatment; at the same time, confirm whether the products have passed earthquake-resistant performance tests, such as whether they are marked with earthquake-resistant grades or provided with experimental reports. During use, avoid unauthorized structural modifications (such as removing walls or adding floors) and regularly inspect the stability of connectors and foundations to ensure continuous effectiveness of earthquake-resistant performance.
