I have a bit of an unusual situation. So, in reality I'm designing some stairs in which the flights/landings cantilever off of columns in the central well of the structure.
All sections of the structural members will be hollow section (beams and columns) and the senior engineer doesn't want to use hollo-bolts or anything similar.
His suggestion for the connection is illustrated in the picture attached.
My concern is, this thin plate connection would need to resist bending plus torsion, would it be any effective in doing so? Or am I overthinking it?
If you have any suggestions on how to design the connection and make sure it works as intended that would also be great!
Is there anybody interested in design of steel beams in torsion?
I hope so, because some time ago, I have developed web application for this purposes and I strongly encourage you to tests!
Web application is available at www.test.be4m.net page. You can use the default credentials, i.e. username: "be4mtest", password: "Haslo1". You can also register yourself and use your own account.
> Beam has one span (simply supported beam)
> Support condition is the fork support
> Beam load is the concentrated force with eccentrity with respect to the cross section shear centre
> Beam cross section is hot rolled I or H section
> Beam cross section class due to bending is 1
It is also important to know, that this application uses:
> Finite Element Method - for calculating the internal forces (linear static)
> SCI P385 Design of steel beams in torsion - for calculating the influence of torsion (degree of torsion and its derivatives, additional bending moments)
> Eurocode 1993-3-1 - for global stability checks (this module is still in implementation)
Any feedback would be greatly appreciated!
Hello Engineers, I am a Bachelor degree student in civil engineering. Do you guys have any workout pdf examples of steel beam design according to EC3. I am not familiar with EC3 so it could be nice to see some detail workout example. Thanks

Thank in advance for your valuable reply.
