Container homes in earthquake zones. The steel box frame handles seismic forces well because steel flexes under stress instead of snapping. Think car frame vs wood fence. Single story models like the 10FT and 20FT are especially good because they sit low with a low center of gravity. The two story villa needs more engineered anchoring. The critical factor is foundation. Setting a container on concrete blocks in a quake zone is dangerous. It will slide right off. Bolt it to a reinforced concrete foundation with engineered tie-downs and it handles seismic forces better than most wood framed houses. Large cut openings for windows can weaken the structure. Factory engineered openings maintain integrity. Our containers come with engineering reports your seismic engineer can use. Email info@atvworldwide.com for the engineering docs.
