T-slot stand design Q's

[MartinM]

Hello! DIY isn't my strong suit but I need to sketch a rough design for a stand builder. I'm trying to create a vertically tall (120cm) with a footprint of 120x60cm stand. There are earthquakes here, and the way the building is designed means that in a strong earthquake, the building will tend to rotate in a circular motion, so that's a point of stress to consider. this stand will be bolted to a shorter stand that will be perpendicular, so it won't be standing alone. The aquarium is a UNS 120U (120x60x60) and will weigh ~450kg.

Here's my diagram, this is what I was considering but I have no idea if it's a good approach. Please ignore the improperly drawn angles, that's why I annotated them!

Top down view of the entire stand which will hold two UNS120's (left stand is 120cm tall, right side is 80cm tall)

And yes, they do need to be joined at 75 degrees not 90 degrees to match the architecture of the home

Front and side view of left side only (120cm tall)

So, my Q's are:

1) What size T-slot?
2) What bracing do I need?

Since the tall stand will be open, I want to go with as few braces as possible (I'd rather use thicker T-slot than more braces if possible). Input is appreciated, thanks!

I used this plan for my stand and it’s super strong. It’s a very common build. I’m not sure how it would work with the slanted side of your stand but thought I’d pass it along. Good luck!

I am not sure what metric size is available in Japan, but I would go with 2 inch, which is a bit over 5cm t-slot.
