Tie-Down for Mobile Tank Structure

[leonsera2]

Hi y'all. First time posting a thread, please forgive me if I'm doing something wrong

I'm designing a structure that supports a tank used for transferring material (it moves on crawlers) from a crusher to a storage area. The structure has dimensions of 3.5x3.5 meters, and the tank base is positioned about 6.6 meters above the ground. My main concern is resisting the large overturning moments caused by sloshing during an earthquake. Specifically, I'm looking for effective ways to anchor the structure to the ground (temporarily, as the structure will need to move around) to counteract these forces. I've considered using chains to secure the columns, but I'm hoping to find a more aesthetically pleasing and efficient solution. Any insights or similar experiences would be greatly appreciated.

Cheers!

Are you planning to anchor something into the ground each time? If so, would it be reused or tossed each time you move the structure?

If you just heavy up the base of the structure, can you still lift and move it? You could consider some REALLY heavy "shoes".

The crawlers will be travelling on a concrete slab, initially planning to have something like padeye cast-ins at the "parking stations" where the chains can be tied to.

Thanks for the input - I'll look into it!

Still not sure for the content. What is the content ? If sloshing is a concern , the content would be a liquid.

. My main concern is resisting the large overturning moments caused by sloshing during an earthquake.

Make calculation and see if anchorage is required. What will happen if the tank topples ? Can you provide a sketch showing the proposed set up ?

Alternatively, one could also consider some means of minimizing the slosh to begin with.
