Help, will my deck support the hot tub?

[Spenlol]

Hi

Is there a possibility for a completely inept/unhandy DIYer to get some help from someone who actually knows something

I have built a deck resting on concrete slabs with beams 45x170
The slabs are placed approximately 100cc apart (I can measure exactly at home later)
The beams are approximately 60cc apart

The deck boards are top decking from Karl Hedin 120x30.

The hot tub is a Serenity 6000 from Hydropool
213cm x 213cm
360kg + 1400L of water so about 2 tons?

Will it work to place this on the deck as it is today, or do I need to reinforce it in some way?
I would also appreciate if someone can explain roughly what formula can be used for this type of calculation. I am really completely lost when it comes to these building terms

Best regards,
Eric

I have no answer, but I can recommend taking a look at an APP from Svenskt Trä, called "Lathunden - Hjälpreda för byggare". There is a lot of useful information about selecting quality and dimensions of timber for various construction projects.

Thanks for the suggestion, I'll check if I find something there.

Addition.

The deck is built with joists running perpendicular from the house, and then the decking boards are laid parallel to the house.
It's not a frame that holds the construction together, if that matters.

The concrete slabs are 40x40 so there is approximately 60cm of air between them.

I would at least kotla between the studs so the whole thing doesn't collapse.

170mm with 1m between supports. That sounds fairly reasonable, but perhaps there is a table to look at. Placing a few pieces crosswise as Per suggests might be a sensible precaution? Otherwise, I would go for it.
