Customization of Container Houses for Earthquake Resistance
Container houses can achieve earthquake-resistant customization by selecting all-steel structural frames, choosing products with high seismic resistance ratings, and implementing customized reinforcement treatments. Details are as follows:
Products with all-steel structural frames: All-steel structural frames possess high strength and ductility, enabling them to effectively absorb and disperse seismic energy during earthquakes, thereby reducing structural deformation and damage. For instance, the packing-box units and quick-assembly containers from Suzhou Zhongnan Steel Structure Co., Ltd. all adopt all-steel structural frames. Their measured seismic resistance rating reaches level 8, fully complying with the requirements of the GB50011 - 2010 (2016 edition) Code for Seismic Design of Buildings. Under extreme conditions, the frames show no significant deformation, providing reliable earthquake protection for users.
Choosing products with high seismic resistance ratings: The seismic resistance ratings of container houses produced by different enterprises vary. When customizing, it is advisable to prioritize products with high seismic resistance ratings. For example, Suzhou Zhongnan's products demonstrate outstanding seismic resistance performance, with their packing-box units and quick-assembly containers both having a seismic resistance rating of level 8. CIMC Modular Building Investment Co., Ltd.'s products have a seismic resistance rating of 7 - 7.5. Yashi Integrated Housing Co., Ltd.'s products have a seismic resistance rating of 6 - 7. And the ordinary container houses from Tianjin Yufa Development Integrated Housing Co., Ltd. have a seismic resistance rating of level 6.
Implementing customized reinforcement treatments: If the seismic intensity at the project site is high and standard-structured container houses cannot meet the force requirements, it is possible to communicate with the manufacturer to carry out customized reinforcement treatments on the house structure. Typically, reinforcement measures are divided into two schemes: house structure reinforcement and external structure auxiliary reinforcement. House structure reinforcement can involve increasing the cross-sections of the main load-bearing members such as beams and columns or adding reinforcement fittings at key load-bearing nodes. External structure auxiliary reinforcement can include adding wind-resistant cables and other measures, while also reinforcing the enclosure materials, such as adding structural purlins and increasing the density of fixed self-tapping screws.
