Can someone help me convert glulam to steel?

[Plupp 398729]

I would like to know which HEA/HEB corresponds to glulam Limträ 115×495 GL30c and Limträ 115×630 GL30c?

Length 9.3m with 3 pillars. I am looking for a steel beam with the same deformation as the mentioned wooden beams.

Many thanks in advance.

LT 115x495 = HEA240/HEB200.
LT 115x630 = HEA280/HEB260.
Gives slightly less deformation for the steel compared to the glulam beams.

"deformation", of course.

Thank you so much

Are there any advantages or disadvantages between HEA and HEB, other than weight and size? Thinking about whether to choose HEA280 or HEB260.

Maybe I could take the opportunity to ask now that I got such good help, if you want to replace a Glulam post 160×160 GL30h and Glulam 115×115 GL30h with KKR/VKR instead, which dimension is directly comparable? Or if you should use HEA as a post, though that might be overkill.

It is usually easier to obtain HEA. When it comes to the columns, you need to know the buckling length, which is probably the length of the column in your case.

It is usually easier to get hold of HEA. When it comes to the pillars, you need to know the buckling length, which is probably the length of the pillar in your case.

about 3m, can be 2.9 or 3.1 too but it's not that exact

LT 160×160 GL30h = VKR 100x100x5
LT 115×115 GL30h = VKR 70x70x4
Given steel grade S355.
