I have a problem:
I've got a single shearing loft. At the moment I attach the surface load to the loft, I get a uniform distribution of the load on the 4 beams and therefore behaves as if the loft was double-edged.
How do I unidirectionally download it? ? ? ?
thank you very much for the info.
 
the distributed load of type area is so... but rather I wonder, and then? What are you doing? If it is to make calculations you know that revit is not able to?! if you have to pass the info to the solutor instead, you should put the loads and load combinations on that

therefore revit does not allow the distribution of loads unidirectionally? ? ?
and in this case, wanting to operate on robots, how to make it download in a single direction? ? ? ?

we did not understand...revit has concentrated and/or distributed free and/or host-based loads. insert it wherever you want and how you want, but the one on area (used for example for accidental loads on the floors) is distributed throughout the area indicated by the designer.

It forgives insistence but it is really my first project.
In a few words, having all the loads agents on the loft that are superficial, to get the linear load agent on only two of the 4 beams is not enough to insert the edge of the loft, right? ? ?
Should we carry out a classic analysis of the loads and apply the resulting linear load on the two beams?

That depends on you. you are the designer, you will decide how to distribute your own loads, accidentals, snow, wind etc...
but I repeat: why do you put the loads in revit? What do you plan on doing after that?
 
in the structural reality of the floors a unidirectional load does not exist! is not the designer to impose it
If you refer to a loft...the armor inside the insole rests only on the carrying beams or even on the parallel beams?
but also the parallel ones... so also the parallel ones accept a rate of the burden that weighs on the loft.

Many programs (perhaps all) of structural calculation allow to attribute a load rate even to the beams parallel to the edge....but it is a design choice of the designer not to attribute it!
and personally I do not see the reasons

in case of revit...as already mentioned....because you want the loads if the calculation will be done with other sofftw....with which to independently manage the assignment of the loads!
 
that a serious load rate even on the beams parallel to the beam I know even if it is actually a small part.
However:
1- my modus operandi is not yet well defined considering my lack of mastery of the software, and by virtue of this I will take the advice to apply the loads directly on robots.
2- with my question I simply wanted to know if the software could automatically provide me with the linear load agent on the two beams considered my single-edge ceiling and the surface load agent on it.

However, I thank you for the answers, I think I understand how to act.

no, it automatically doesn't give you anything.
Also in demo last week, an engineer believed that automatic revit would insert the weight of the superstant elements...but if so, if it were all automated, that is to make us the strutturist? we pee a Chinese or an Indian paid 2€/h to push buttons!
 
you are talking about a software here in Italy still unused. every question is lawful!
 
If it's all automated, what's the strutturist doing? we pee a Chinese or an Indian paid 2€/h to push buttons!

maybe it was just what he thought ... maybe putting us a new graduate/diplomato Italian that in free internship costs less than a Chinese.

I have the same svitalone problem, in the sense that with other software type sap 2000, I have the possibility to insert the loads (area) in kn/m2 defining a shell membrane with zero weight and assigning a load of area (uniform to frame) in the direction (one way) depending on the edge of the loft so as to load the main beams. In this way I avoid loading the individual beams with uniformly distributed load. Now I wonder if it is possible to do the same with revit or with robots.

Thank you.
 
Yes, you can, but what I keep not understanding is why you want to do it on revit? These things must be done on the solutor, not on the modeler!

was to understand how far the bim concept goes. But I would like to know how to do it on the solutor at this point, that is, on robots.

and where is the difference?
 
antsalz said:
the difference is operational because it is faster to load the whole structure. Whereas having large structures and beams of different light could be very useful.

You're always talking about sap 2000, aren't you? ....... haaaaa, here!!
It is not always so....the vast majority of calculation programs:
1 - we evaluate the load of the loft, proper pp, accidental, etc., for square meters
2 - the loft is inserted by attributing the loads of point 1 -
3 - the programme automatic charge the beams according to information in 1 - and 2 -

better than you look at some calculation program professionalthe various production houses always make available a valid currency version for 30 days.

ps I don't know the sap 2000.... it always gave me the impression of being a program used purely in university environment....I can also wrong myself in this.
As an alternative, I know, in a semi-detailed way, at least 5 and I have chosen a definite 1.

I understand the generic procedure, but the robot procedure, can anyone describe it to me?
