Ok Thanks

Please be aware though that I'm in the UK & need to use "British Universal Beams"

Hi

I took the beam size to a guy to fabricate & fit the beam for me, they said the size wouldn't be up to the job because of the span. I have a hunch I've maybe given you wrong info. Maybe if I give you more info about what I'm doing & if you're willing to help I'd be very grateful.

I'm opening a yoga centre where I'm going to teach Aerial Yoga, (people suspended in fabric Hammocks).

There are 3 huge I-beams that run across the width one in the middle & 2 at each end, I want to fit smaller beams that run the length of the studio at right angles to the existing beams.

I want to fit 3 beams either side of the middle beam 6 in total. When gave you the figures I was going to spread the load of each hammock across all 3 beams using timber or smaller steel. Now I'm thinking the simplest way to look at is that the longest beam span will be 4.8M which will support 3 Hammocks I was working on people weighing 100kg max, but when I gave you the figures I didn't allow for the dynamic nature of the moving hammocks. The other thing you might need to know is that I would use a 3ft scaffold pole above each hammock clamped to the beam so that each end of the hammock can be rigged about 2ft apart.

If you can help I'd be very grateful, I might need to see your calculations if that's possible.

Thanks James
