How to determine Steel Grade? [BS 5950]

[HarryKoh]

Hi guys, I'm still new to this steel structure, would like to ask if we know the section e.g UB 305x102x25, how do we determine the steel grade (S275, S355, etc)?

Thanks.

The beam section is only the shape, the steel grade is separate and not controlled by the section.

Hi, thanks for the reply! I would also like to ask how do I count the selfweight of the steel? Take UB 305x102x25 as example.. so the steel density multiply the area of section? Thanks!

You model the beam's self-weight as a distributed load based on the beam volume and density.
