Thanks, Diego. It is a great tutorial! Could I get the file ? Thank you
Sure thanks! here's the link -> drive.google.com/drive/folders/10l7nw2w-swjtHmhMSwkFhHRQl-kkXp3y?usp=sharing
THank you for sharing Diego! :)
Hi Diego, I am really enjoying your videos, it helps me a lot with my thesis to graduate. I was wondering, is it also possible, to optimize the cross sections by doing the following:
- connect a slider to the list item component, and the list is connected to the cross section range component
- then connect the slider to galapagos, so you do not use the cross section optimization component
I have a really big script with a lot of groups, and I think it might work better if i do it this way if that is possible at all
Hello, I'm glad my videos are helpful! You can certainly try to optimize the cross sections that way, but I think that is sort of an overkill solution. The optimize cross section component always selects the optimal cross section which is the one with highest utilization under 1.0 (or another maximum value you set). You can also set groups with Karamba so all members of your groups get assigned the same cross section. This direct approach can get more complex with statically undetermined structures, because the force distribution changes when the new cross sections are assigned. But in my truss example that's not the case. It sound like you have a fun project so good luck anyway!
@ Thank you for your reply Diego! I understand your concern about my approach and with the group labels I will go for your option. With the Karamba Manual I think I will be able to figure it out.
My thesis (at TU Delft) is fun but a bit challenging from a geometrical point of view, if you are interested to know:
- I am designing offices that can be fully demounted, relocated and remounted in a different configuration to become apartments in 30-50 years time, in such a way that the materials are utilized to the highest percentage possible
- to do this, we must be able to change:
1: floor-to-floor height, because offices have 0.5 meters lower free height by code regulation. If we can change the f-t-f-height, we can save materials
2: the braces will of course have eccentricities when the f-t-f-height goes up, i am using LCA for example to figure out how bad that is
3: the live loads of apartments goes down by 30 percent compared to offices. So i am designing a floor grid where the number of beam configuration supporting the slabs can be changed to have high utilization in both lifetimes
4: the number of columns must be changeable, because the floor live loads decrease, and the number of total floors too (the total building height remains the same, but the f-t-f-height goes up, so less floors in total)
So basically it is mostly challenging in terms of geometry modelling. Finally, I am comparing these changeable buildings to:
- a demountable but slender office only, that will not be used as apartments later (Q: how much extra materials do my special designs need to make the apartments possible?)
- a demountable building with the highest capacity in floor loads and f-t-f-height, so the building meets the requirements of both offices and apartments (Q: how much less materials do my special designs use, and is that reduction worth the extra labour costs of remounting the building in a different configuration?)
If you find this topic interesting, please let me know, then I could sometimes send you some updates.
Happy Easter!
Great tutorial. Thanks for sharing amd any method to Strand7 or Strus7 in st7 file ?
Thanks! I don't use those programs, but if they have an API, the approach should be similar
Great tutorial! Thanks for sharing.
Hey Diego - would I be able to get the file for this tutorial please?
Hello Jacob, sure just let me know your email adress to send you the file please!
Nice work Diego.
Here is my email: m_j_ipa@yahoo.com. Thank you
sure, done! Thanks btw!
@ Thanks🙂
thank u
Hello diego can i get the file please and thank u for this great tutorial
sure just write down your email adress please!
Hi Diego, Good Day!!
Is there any similar tool or plugin available which can be integrated with ETABS for optimizing the structural walls or columns?
Thanks.
Actually, I´m planing on doing tutorials of those particular topics:
- Column Optimimzation in ETABS
- Interoperabilaty ETABS - Grasshopper
Hopefully, it will happen in the next 30 days :)
Karamba me gusta tu pachanga!! 😁
thank you
hello, is it possible to do truss connections analysis with Grasshopper?
hello, you should probably take a look into the KarambaIDEA plugin
Great tutorial, Diego! Could I get the file ? Thank you!
sure ! but I need your email address
@ , my bad, Diego. jingkong7388@gmail.com
sent!
I have a question, how do I make a Rhino view like you?
Thanks
that's the topmost viewport plugin
@ Does it work on Rhino 7?
@@tonghoang2628 it does for me!
@ thanks u, now, i same
dear diego ,kindly if you can tell me how to get optimization with the same cross-section in each member? am struggling with this part in my project?
thank u !!1
Hi, you need to firstly define those members in the "Line to Beam" component with an ID and then you have to connect this ID with the Group parameter of the "Optimize Cross Sections" component.
@ i got it thank u so much !!! actually using this software for a project with and am struggling with something else kindly if i can ask you again ?
@@mammerisafae5410 if it's quick questions like this one, yes sure, preferably over youtube comments!
@ i want to know a method to record cross-section changes!!
maybe i can explain what i have done! am working on dome structure(ribbed) and I have defined 2 elements rings and radials,i optimized both separately with OptiCroSec and then start running Galapagos in order to find the optimal subdivisions (Genoms) of my panel (Quad) with a minimum of mass (taken from OptiCroSec) .so i got the min mass with optimal subdivisions but the cross-sections have changed and i don't know how can i figure it !!! kindly if you have an idea help me !!! thank u
@@mammerisafae5410 this looks very intereseting! but unfortunateley, it is not such a short question. if you want, you can send me your script per email to dapellaniz@gmail.com and I can help you out, but then I would have to charge you my consultant fees...
how did you get your rhino viewport in grasshopper?

@This is amazing ! Thanks for sharing
Thanks, Diego. It is a great tutorial! Could I get the file ? Thank you!
