Combining steel and wood can be problematic. It often requires drilling holes and bolting. Sometimes, welded extra flanges are needed at the beam's short ends. Above a beam, no top plate is required. If you utilize the entire space above the opening, I believe you can fit a glulam beam. It will be much simpler and cheaper. Instead of HEA 220, you can use a 215x360 mm glulam if you want to minimize the beam's height.
The opening will be 600cm. The height I have to work with upwards is 360 mm. But that's tight, and if I've miscalculated by even a millimeter, it will be troublesome.
I suppose it will be a HEB or HEA then?
Or what do your calculations say, Justus?
If I could manage with an IPE 30, it would smell like success.
I will scan in grandpa's drawings, including construction drawings, this week so we can take a deep dive
Good question. With a distributed load of 13 kN/m and a span of 6 m, the load per support is 39 kN. An IPE 330 with a support length of 300 mm and a width of 160 mm results in a support pressure of 785 kPa, i.e., approximately 8 kg/cm². In my old handbook Bygg, the compressive strength limit for concrete hollow blocks is given as 42.5-50 kg/cm², so it should be fine. Apologies for the old units, but it was the quickest way.
