Hi,
I think you have a better option if you write your question in English.
Anyways, from the translation, you need to create an arch shaped H beam.
If it is horizontal, you can simply draw it using the arc tool after you start the beam tool. If it's vertical, an easy way is to use the truss tool and modify the profile.
