Hi,

 

Is it possible to combine a particular case with the envelope to yield maximum/minimum results.

This would save time from creating more combinations.

 

Thanks

I recommend you to fix the values of the Egyptian reinforcing bars (ECCS_203_2001) to be like that pic.

 

 

We usually correct it manually from it's .Xml file it's not working to change values from the program.

The mild steel yield stress we use = 2.4 E+08

and 

The high tensile steel yield stress = 3.6 E+08

Hi.

I see someone had posted this in 2016 and I would like to support this request. We do calculations on drilling structure in accordance with the API Spec 4F (API = American Petroleum Institute). API released an addendum suggesting that connections using tubular sections shall be checked against the requirements of AISC360-10.

Doing this manually is just not realistic. considering the multiple beam and load cases.

I tried migrating a model from Robot to Revit - it doens't work.

So our only choice at the moment is doing it manually or subscribing to other software. Since you already have plenty of EN connection code in Robot, why not implementing AISC? (since you also already have AISC 360-05 + 360-10 steel members code checks)...

Your earliest response will be much appreciatedas we're currently looking at solution in that regard

thanks in advance

If a country regulation is not in RSA then you can not define a seismic analysis. So you need to define a spectral analysis but in the dialog box for this analysis there isn't an option for introduce the eccentricities. This option need really to be implemented in the new version.

 

Best regards,

One of the TOP VOTED themes is Brazilian Codes. 

My suggestion is to Autodesk pay a brazilian specialist to work for a short time with your Developer Team to write all the codes necessary to use RSA in Brasil.

Don´t think that any Engineer will work with one software to model and other to calculate. They will invest in only one software.

When i import an AutoCAD file in RSA, some times it gives error and the program crashes and closes.

I then realized that i should delete all hatch pieces and other regions and text ,..... etc keeping only line and polyline objects.

I wish that error can be fixed in the upcoming version.

Another thing,

All arcs drawn in AutoCAD is converted into lines when i import the file in RSA.

I wish this also will be repaired to get full view of the arc as it is drawn in AutoCAD.

erformance uildingDear all

I have some urgent ideas, I wish to be taken into account in the next version of ROBOT as:

1- Robot must be capable to model concrete structures exposed to direct fire for long period and do the required analysis to show the stiffness degradation and residual capacity of concrete elements.

2-Robot must be capable to define the nonlinear properties of concrete, steel ,...

3- Robot must be capable to do a complete distributed plasticity analysis of concrete buildings not just in a certain point, to show the real behavior of a structure under extreme loading conditions.  

4- Robot must be capable to do the required retrofitting design of unsafe concrete elements by concrete jacket, steel jacket and also FRP. 

5- Robot must be capable to do performance criteria of a building (performance-based design) after doing the nonlinear analysis by distributed plasticity?

Please take care of the previous ideas and I hope to be in the next version of ROBOT. THANKS

Hey

I just started to use this program, and it is very frustrating that two programs made by the same company use 2 different graphic symbols and interface.

why does the "cut" or "copy" or any other symbol in Robot are different from the well designed symbols in Revit or Autocad?

 

make it more intuitive to the users that familiar with Revit and Autocad by adopting Revit's visual interface design

Hello , i wanna say that there is a new algerian DTR C2.47 , it's C2.47/NV 2003 instead of C2.47/NV99. it's practicaly the same with some modifications, so i hope that your company will make changes about it and will also include 3D wind generation of this code.

About the steel connections. i hope that will be improvments cuz RSA doesn't give all steel connections.

and it's the same for the foundations , it's very complicated to calculate a shooting foundation.

I have noted that when ones send your design model from Robot back to Revit with results it can't be scheduled. The "results explorer" works great to visually view results but still doesn't update the analytical results of each member, it has to be done manually. It seems like to analytical results are not connected to the properties of the analytical members. For example, this would especially be handy when one does column load-rundowns to simple extract the results through schedules of all columns at each level.

Similar to panel maps and Panel cuts in order to solve this issue is to include the option of normalizing type on core walls diagrams as shown in the picture and to leave the choosing between of them to design engineer to choose the most suitable for him and This option also to be activated for calculating the reduced forces and moment in panel cut .

Hi

 

If you have mesh which need manual correction like on picture. Choose master node and than chose slave nodes which will merge with master node and refresh mesh to delete zero FE elements. It would much easier than choose each node and move it manually.

Hi All,

As we know that concrete properties will change during the time.

Its related to creep and shrinkage which will affect the modulus of elasticity during this the considered time which is will cause significant changes for high rise building when we check the column shortening.

I propose to add the calculation of the settlement of the foundation for “foundation design” for the code “"Fascicule N°62-Titre V" because we have already the possibility to use the pressiometric curve to calculate the allowable stress.

 

If you add another column for the pressiometric modulus it will be fascinating.

 

Thank you.

-------------------

Je propose d'ajouter le calcul de tassement dans le module « semelle » pour la norme "Fascicule N°62-Titre V" puisque déjà il y a la possibilité de calculer la contrainte limite admissible en se basant sur les données de l'essai pressiomètrique.

 

Merci.

This is my idea of a thing. Look at all the countries, in next 5 years most of countries worldwide will focus on implementing BIM in law (IFC format etc).

Do you know which thing I really hate while modelling? Spending time on calculations. It takes so much time to wait, when the model is big. Today I was looking for the answer, why there is so slow calculation in Robot. Here comes my answer: reaf.png

 

So: Robot has implemented some solvers, which use CPU. My idea is GPU. In last few years gpu companies like Nvidia has been working with many scientists on linear solvers supported by gpgpu / cuda (some nvidia names). Now think: i calculate my model of highrise building with 4.8 GHz i7 7800X in about 2 hours. This is terrific. If one day some say "hey man, there is a software that uses GPU solvers" I imagine that my model would be solved in 25 minutes. I know some stuff now. If there is any person that reads my idea, be sure: this is a way of improvement in model calculations. Give to the people the most powerful structural analisys tool ever. Look, there are ready solvers to be implemented:

You are the big Autodesk. Dont get burried like Nokia or other great companies, who had the chance to rule the industry, but they ignored many improvements, solutions available in around. Have a nice day!

Please,

 

I wont give up!! Man Mad

 

Add the Brazilian Codes NBR 6118 for Reinforced Concrete, NBR 16055 for Concrete wall castes , NBR 8800 for steel, NBR 14762 - Design of cold-formed steel structures.

 

In Brazil is common change the default codes materials like EN 1992, ACI, AISC as seen photos below.  These are similar but not equal 'cause the code check parameters isn't tehe same and complementary checks is needed.

 

I really believe that will be thousands of new users if exist the possibility to add some Brazilian codes (6118 and 8800 will be fantastic Smiley Very Happy)

Results signs

by Muhammed.OPERA on 08/05/2017 9:18 PM

I recommend putting an option which we can change results signs from.

For example: in our university studies we use +ve sign for tension internal forces but, here in RSA the positive sign indicates that the member is subjected to compression. In the slabs too, we used to use +ve moment sign for the lower moment and -ve for the upper momment.

that conflict makes it difficult for many new users to understand results.

So, i recommend putting new option that we can reverse results signs from.

User Interface

by Muhammed.OPERA on 08/04/2017 4:49 PM

I recommend changing the user interface of the program to be like any other Autodesk program, just replace these many toolbars with ribbons like AutoCAD. That will make it easier for students and new users to learn the program.

when we import an AutoCAD drawing, it is imported as a smart JPG (background) that i can show or hide any layer of it.

This is great but, why don't you add an option that we can import beams from certain layer and supports from another layer instead of importing it just as a background.

Really it makes me angry that i can find it in other companies' programs and not in Robot.

Hi all, do we have any kind of macro or API or any other way by which we can use excel as the tool for making modelling elements in ROBOT. Like i give coordinated in excel and there can be a command which directly makes that element in ROBOT ?
