efficiency and tenacity of composite alveolar beams

[odisseo 18]

I apologize if I ask the question, I happen to see that in some structures made of metal carpentry, are used alveolar beams, ipe beams or np, properly cut with plasma and then assembled and welded. I wondered at the structural level, are they efficient to bear loads of push-ups and stresses to which they are subjected, such as, laminated beams? with what criterion would they be conceived? as they are tested to make them suitable for the use of buildings, as they affect the shape and welding on the same, when they are subjected to tension forces and stresses when loaded. and especially what do you think of it as technicians? Thank you

on the site of arcelormittal you will find all the information you need, and also the calculation software:then what to say, well they are beautiful... they use very much architects for large covered areas, fair spaces, airports etc.

these beams have the advantage of reducing weights and allowing the passage of plants.
then there is also the aesthetic aspect.
I would follow the advice of @ cadinpiedi and I would use the program.
but if you want to enter more specifically: the check to the cutting of the beam is actually the checking of the souls (and automatically check the welds too).
I would add Soul Compression Verification to avoid local instability.
for the calculation of the deformations the moment of inertia will be an average between full and empty tract (maybe weighing it on how much it is full and how empty it is).
you can safely entrust it to the wings.

What kind of welding would be done? practically cutting them by assembling them and climbing them doubles the section, but halves resistance and toughness. rightly if you have to support a light cover ok, but a loft, a loft or a structure subject to high loads maybe concentrated?

in inglese si chiamano credo cellular beams- castellated and cellular steel beams ? giusto

I'd like to get into this. Thank you.

I repeat, the arcelor software can calculate both single and single beams. keep in mind that it is the same arcelor to perform cutting and welding for project-formed beams, with all warranties of the case.

I apologize if I insist on compliance with regulations, forgive me if I insist on the views used in America that are wide-ranging from us only in particular structures, excuse me again and thank you for your clarification.

 

[Cadinpiedi]

personally I have never made a project, but only studies. It seems therefore useful to ask the same arcelor to clarify every doubt.

 

[odisseo 18]

thank you for the information I apologize if I insisted

 

[Cadinpiedi]

There's no problem, I can only tell you that the strutturist to whom the studio proposes told me that the standard software he used did not handle that type of beams, but it's been time.. .

Thank you again forgiving me if I've cheated on you. Thank you.
