Hello
I'm working on building a stable and have now come to the point of installing an intermediate floor for the hayloft. Initially, I had thought of a row of posts under the middle of the joist. Then I found two HEA120 beams lying on the farm that I now think might be used to support the loft floor to avoid the posts underneath. I know nothing about steel beams and how much load they can handle, so I thought someone here might be able to estimate whether my idea could work.
The conditions are as follows: The joist is 5.4m wide and 6.5m long (actually longer but will have a load-bearing wall a bit out towards one gable, so there will be no span issues there).
The hayloft should support the weight of about 3 tons of loose hay spread out over 46m2 of floor area, which gives about 65kg/m2
I have therefore thought of building the joist as follows: 45x220 beam cc60 5.4m long. Below, 2pcs 6.5m HEA120 beams with appropriate spacing between them for support. As flooring on the loft, it will be grooved 2-inch planks.
I understand if it doesn't meet the standards according to today's building codes for residential houses, but for a simple hayloft, I am curious if you think it will work.

The two HEA beams each need a post in the middle underneath them to be sufficient. The span is a bit too long.
I got it to about 50 mm under my assumptions about load (low) and distance.
If you reduce the span to 5 m, it might work for the small loads you are considering.
Three beams are obviously better than two. It makes it more pleasant to walk in the loft.
