Robot Art Gallery - real structures and their models

[Artur.Kosakowski]

As suggested I'm starting a new topic intended to show what you dear Robot users achieved with little help of RSA

Hats off Mustafa, very impressive!.

Awesome Mustafa!

It is so inspiring...

I am interested in how you utilize RSA for such large buildings, ie:

1. How do you set up the initial model? Do you use dwg background or Revit?
2. How do you verify results? I am busy making myself a RSA model audit checklist to verify things such as:
   • Hand calc structural weight vs RSA calculated weight.
   • Applied loads vs hand calcs (additional permanent, Imposed, seismic, wind, etc)
   • Checking for unusual deflections
   • Boundary conditions
   • Mesh refinement
3. Do you split slabs according to load zone to make applying and modifying loads easier? Or do you model floor using one panel?
4. Are your floors typically post-tensioned? If so do you take any different steps to model them and how do you model wide band beams?

Sorry for so many questions...

Hello @mustafahesenow

How can you analyse more than one building in one model without getting a "separate structure error"?

Thank you in advance

Hi @mustafahesenow

Wow :-).

Seizing the opportunity: Have you received my private message?

[mustafahesenow]

Hi @Artur.Kosakowski

Yes my friend I replied it .

Please check your messages .

Very nice mustafa! congrats...

@mustafahesenow

do you still sleep in doing these magnificent structures of yours. It is really amazing. I would like to suggest to create a book on this. I guarantee you it is a best seller! Just pick a challenging project of yours and explain everything from inception to completion and probably if any top government officials from Qatar or anywhere in the Middle East read your book, this will be the start of something big for you. They might bought ARSAP from Autodesk and made you the CEO and we are all very happy. Mark my word!

¡Holy crap! 

What an amazing project my friend @mustafahesenow

One of the best project I've ever seen. Autodesk should write a post about it on all their websites and blogs, just saying.

Keep up the good work.

Amazing! Dream to have a computer that can actually process those models!!!

[acmprojetos]

How do you model this structure in the Robot?

[MRizea]

I've just seen this post! Impressive work guys. I'm a beginner with RSA, but i love it. Thank you all for sharing your work and being an inspiration.

Hi everybody,

here comes another project that I've done in Robot some years ago, it's a mixed use tower located in Oran, Algerie.

It's a 23 off-groud tower with 6 undergroud levels of parking. I used Robot with several APIs to run all the analysis, specially SpiderPro by @Romanich, CFT for Robot by myself (for the correct design of concrete fillet tubular according to Eurocode 4) and other APIs from forum.

The most interesting analysis was done for wind analysis for Robot, in comparison with the local regulation loads.

@StefanoPasquini6790 : Hey Stefano, I was curious looking at your model here. I always thought that the slabs needed to be broken up into "pieces" (i.e. each corner of a "piece" or "polygonal panel" is connected to a wall or column) to get an accurate analysis as opposed to modeling it as one whole piece as I see it in your model. Does that really matter or was I always modelling my slabs in an extremely tedious fashion?

Amazing thread, I discovered a hidden world! We have some RSA stars like @mustafahesenow  @StefanoPasquini6790  @Rafacascudo, just to write down the ones I remember.

I would say thanks to many people that help "normal" user everyday, nevertheless some users in this thread posted some interesting question like  @Anonymous in post 183, but no one answered. I have also my question to ask, and I'll write them at the end of this post. What I would like to encourage all of you expert in RSA to do not forget to help "normal" user in answering. If we want to really #saveOurRSA we need to help each other without any loose.

Here my requests:

• could you describe your workflow? Do you either start design the model from zero or you import it as a dwg/rvt?
• I have seen several huge model in RSA, how do you deal with them? How you verified every single beam/column?
• Would be valuable if you could share even small model to the community to check how a model needs to be properly done in RSA.

I hope I will find some good hint from this post

[Rafacascudo]

1- Yes , when available ,mostly DWG,DXF . Revit only for buildings and generally the conversion result is terrible

2- Despite lots of requests for almost 20 years , still No brazilian codes on RSA . So checking for me is by hand , spreadsheets ...

3- Complex models like those are generally not allowed to be shared by the contractor.

Hi nice work I want ask torsional irregularity we can find when uesed the dynamic analysis
procedure were to be used, the values of Ddmax and avg Dd would have to be found
for each dynamic mode,and find amplitude in direction ux and uy and uz?

These structural models are really amazing! Did you develop these projects? I live in Rio de Janeiro, I am a Civil Engineer, University Professor, and I like Structural Analysis very much.
