Hello! I have a patio built partly on concrete pillars and partly on slabs (due to hard and rocky ground). It is 10m long and 5m deep, with the first beam attached to the house, followed by 2 more beams. The lumber is 195mm for the beams, 145mm for the joists spaced at 600mm centers, and the deck boards are 120mm. We didn't build the patio ourselves.
Now we're soon going to have a wedding and are thinking of setting up a tent on the patio and having 20 people. Can the patio handle that weight? There will also be tables and chairs. It feels a bit unstable when walking on it, but maybe I'm just worrying too much. How much weight can the patio support? I don't want it to sink...

Spontaneous answer yes. No problem. Half a meter of snow on your patio weighs 1500 to 2500 kg. 20 people at 80 kg each weigh 1600 kg. It's fine.
It creates completely different dynamic loads with people who might be dancing and jumping for joy, not comparable to the weight from a static snow cover.
What your terrace can handle is something for someone else to calculate who understands such things and is not just guessing.

Yes. You're absolutely right about that. I didn't think that people might jump and dance, of course, if it's an event. The simplest solution might be to bring in a constructor, or have the party on the lawn?
The information you have provided is not sufficient to make the calculation. How many plinths or supports do the beams have and what are the distances between them?
The foundation blocks are approximately 2.20 apart from each other.J justusandersson said:
@Amaryllis92 You forgot to answer both questions, number and distance.

If you are scared, place tiles between the pillars and add extra support under the joists.
