I have create a composite bridge (steel+concrete). I have followed the tutorial from 2022 on your website.
This tutorial do not talk about effective flange width, see EN 1994-1-1 or EN 1994-2.
I found a old question about this and it says that it need to be set manually for the T-beams cross-section, according to EN 1994.
Is this still relevant in Sofistik FEA 2022? If I change the cross-section in support areas I don’t get enough self-weight from concrete (and formwork?) if I follow the tutorial. I think that the formwork will be to low also in the support areas.
How do I get the linear transition for the effective flange width between span areas and support areas illustrated in EN 1994?
