Container Modifications:
Shipping containers have monocoque bodies. The corrugation panels (roof, sides, and back), floor, purlins, front doors, frame, and rails form an integrated structural skin. They are strong and made to carry floor loads far in excess of what is required for typical home construction. But, when you modify them, cutting holes or penetrating members, they are weakened. Regardless of what level of modification your shipping container home design calls for, it is recommended to review with a structural engineer or architect.
As we said above, when cutting a shipping container or removing any of the paneling, it's structural integrity is compromised. As an extreme example, consider the removal of all a container's corrugated paneling along the length of one side (see the images below). Without reinforcement, the container deforms and then fails structurally. As a general rule, whenever you remove portions of the panelized corrugation, steel framing will be required to frame out the opening. In addition, column and roof support will be necessary depending on the size of the opening(s) and roof/wind loads.
Steel cutting, framing, and welding is a large part of shipping container home design and construction. Typically, steel construction is not used much in single family or smaller home design because of expense. Cost of steel vs. wood/light gauge framing is substantial and the labor cost for steel vs. Carpentry is also higher. To combat this, it is best to have as much of the welding and reinforcing done off-site before setting the containers on site and starting the interior fit-out. Most (if not all) container re-sellers have the facilities to make these modifications. If you don't have experience in metal work, or are not hiring a general contractor, you should plan on doing most of the container modification work off-site prior to delivery.

| Conclusion:Stacking ISO containers 10 high on land is reasonable, and stacks as high as 12 may be possible depending on the type of container purchased and on the loading of the container with Off-Axis detector elements. For a final detector design, good engineering practice would require that the corner posts of the selected containers be loaded to failure to more accurately determine the safety factor of the stacked array. |
