test calc GUI V014.76
Container dome anchoring calculator
Answer each section to describe your container dome. Anchor recommendations appear once every required input and calculation method is complete.
1. Scope check
One page for both. Measured distances lead with this choice and still show the other unit. Standard container sizes, and the 8 ft container width, stay in feet.
2. Let’s build your container architecture
Container layout — representative dome bay
Build Row A and Row B, then check the live architecture as you go. The default order puts 20 ft containers first, but use the ↑ / ↓ controls in the live graphic to match the actual FRONT → REAR order on site.
| Qty | Container length |
|---|---|
| 20 ft | |
| 40 ft |
Row B
Yes means the container sizes, sequence and longitudinal positions match Row A.
| Qty | Container length |
|---|---|
| 20 ft | |
| 40 ft |
2.4How are the two rows aligned?
This shifts the rows longitudinally in the live architecture. The calculator then determines whether the Front ends, Rear ends, both ends, or neither end physically line up.
3. Row distance
No is the default: you enter the distance between the rows, and any end containers must fit within it. Choose Yes if an end container’s length sets the distance, then pick which end.
Choose Yes if the front end container’s length sets the gap between the rows, or No if the rear one does.
Distance between Row A and Row B
Choose 20 ft, 40 ft, or Other. Feet and metres both stay live. Any end containers you add below must fit within this distance.
Front end
| Qty | Container length |
|---|---|
| 20 ft | |
| 40 ft |
These containers form one continuous front end row across the two parallel rows.
This makes the front end container set the row distance (3.1 switches to Yes). Inside positions set the inside gap to its length; Outside sets the outside width. Switch 3.1 back to No to return to the distance you typed.
Rear end
| Qty | Container length |
|---|---|
| 20 ft | |
| 40 ft |
These containers form one continuous rear end row across the two parallel rows.
This makes the rear end container set the row distance (3.1 switches to Yes). Inside positions set the inside gap to its length; Outside sets the outside width. Switch 3.1 back to No to return to the distance you typed.

4. Dome geometry & coverage
The dome springs from the inner top edges of Row A and Row B, spanning the clear gap between the rows.
Dome span comes from your rows: the inside gap (inner edges) or the outside width (outer edges), as chosen above. Dome apex/rise: the height of the dome at its highest point above the top of the containers, not above the ground.

Dome length
Choose 20 ft or 40 ft, or choose Other and type the length in metres or feet.
4.4Dome position
Use the dome-position slider in the live architecture panel. The orange dome footprint above updates immediately along the shared FRONT → REAR datum.
4.5Dome structure dead weight
Enter the actual permanent weight of the dome frame and cover. Use manufacturer information where available. This downward load is part of the structural calculation; it is not a Safety Buffer or an anchoring capacity.
Dome dead weight: not yet entered.
5. Dome ends & openings
Partial enclosure %: for “Partial from top”, the slider is the share of the area that can be covered, measured down from the dome apex, and the drawing shows exactly that area. Each end is judged on how much of it is still open: an end counts as closed only if what is left open is no more than 0.5% of the end and under 0.37 m² (4 ft²). An end container that sits right at the dome end closes the bottom of it; a short container in a wider gap closes only part of it, so that end is partly closed. Door/opening questions are shown only where the enclosure forms a full-height wall to ground.

7. Mechanical connections — per actual joint
Only joints that physically exist are shown. Hover, focus or tap a joint question to highlight its exact location on the live architecture.
8. Extra weight fixed to the containers
8.0Empty container weight
Empty weight is counted automatically: 2,300 kg for each 20 ft and 3,800 kg for each 40 ft. If a container’s plate is different, add the difference in the additional weight fields below.

8.5Extra weight for each container
Use the compact kg column like a spreadsheet. Press Enter or ↓ to move to the next container. Pounds update automatically.

9. Wind, ground, snow & Safety Buffer
Safety buffer: 0–100%. 100% doubles the raw result.
Use kPa for metric, or psf for US and Canada. Both are accepted.
10. Technical info
The working figures behind the shopping list. These stay hidden unless the box above is ticked.
The figures appear here after a wind speed is entered.
11. Shopping list
The parts for this layout. Pack prices already include the pack discount on the product page, and that price is what goes into the cart.
Want the list on its own page? Display opens it in a new tab, and that page has the “Add these parts to my cart” tick box.

Anchor count: appears once you reach Wind (Section 9)
This panel shows your total anchor count once you’ve entered your wind details, and it updates live as you change any field, so you can see the effect straight away. A full parts and shopping list appears at the bottom of the questions on the left.
Single confirmation view — Row A and Row B shown together.
