Hello.
I have planned a deck that extends 4.2 meters from the facade and is 6.0 meters wide. I placed the posts 0.4 meters from the facade, 2.5 meters between each, and about 0.5 meters in from the "end sides" of the deck. I laid out three such rows where row 2 is 1.6 meters out from row one. Row 3 is an additional 1.6 meters out from row 2. On these "rows," I have laid out beams, 45x190 mm. As joists, I have used 45x170 cc 45. The decking to be used is 28x120 mm.
Now to my question. Should I add additional support for the beams? Perhaps double them? Or just place a lecablock as support? It feels really stable and nice as it is now, but when I read here, I became a bit uncertain... Maybe dig in an extra post between the ones that are already there? Suggestions??
Thank you in advance!

A quick mental estimate suggests that it seems sufficient without additional support.
I assume you have bearer beams with posts every 2.5 meters and that the floor joists have a span of 1.6 meters. Or are you planning to do it the other way around?

You have understood it completely right. The thing is that I should not attach it all to the foundation of the house; it's mainly the horizontal shift I'm pondering. But it was nice that you could confirm it all 
I'm pacing back and forth about extra support I have an excellent chance to do it now, but it costs me a bit with the shovel... though it's free exercise... I saw a table, it's circulating in this forum where the measurements you just mentioned are guidelines for my dimensions. Fun that it was such a good hit by estimating
I will think about it a little more, will post a picture when everything is done
