Hi Max,

I don't know how can you do  that on grasshopper (I hope that someone can give us a good, answer..)

I don't know if it can help you but I'm doing my thesis on this kind of structure, and I  do that with grasshopper Smart Structural Interpreter and GSA. 

Bye

Hi Guido, thanks to your answer, of course i'm interesting about your work on gridshell structure. If you can send me something of your thesis, maybe it can help me.

Tanks a lot

Hi Maxime,

From what I saw in that video the author used Kangaroo to generate the shape of a grid shell.

I do not know how could you do that in Kangaroo. Maybe some other user could help you.

But you can do the same thing in Karamba, using the "Large deformation analysis" component.
Here is an example:

thanks a lot Djordje, this is really interesting, but i have a problem I do not understand what I have to add the file to work properly. I have yet to install Karamba. Do you have an idea?

thanks a lot Djordje, this is really interesting, but i have a problem with the file formfinding1, I do not understand what I have to add the file to work properly. I have yet to install Karamba but i have a problem with the "assemble model" wich is red. Do you have an idea?

Quit Rhino and Grasshopper, install Karamba (download it from here - choose between karambaFREE 1.0.2 (32bit) and karambaFREE 1.0.2 (64bit) depending on your system).

Then run the Rhino and Grasshopper again, and open this file.

If you still have problems, post it in Karamba's group.

Hi Max,

I've actually just returned from a workshop for the design of a timber gridshell using Kangaroo, and I've been looking a lot recently at ways form-finding them (and in discussion with several different groups about this).

I'll make a more in depth post very soon about some of the different techniques we've been using, along with example files.

Here are a few examples to get you started.

There are a number of different approaches and ways of combining them, and these are simple versions of a few of these, but hopefully they give some idea of what is possible.

The one 'drape2.gh' drapes a square grid over a predefined form (similar to the what is described here: A design method for timber grid shells)

The one 'Catenary1' is based on the hanging chain approach, as used for Mannheim (particularly appropriate when the dominant load is self-weight, which may not be the case with smaller grid shells)

The one 'bending2.gh' introduces simulation of the bending (and I think is most similar to the approach used by André in the video you linked to above)

 

I think things get particularly interesting once you start looking at how these approaches can be combined, or iterated between, depending on your design process and what exactly you want to optimize for. Anyway, as I say, I will write a more in-depth post on this soon...

thanks a lot to your answer djordje !
Daniel, your answer is really really interesting, the file drape2 is a good method to do gridshell, i wait your post, i'm sure it can help me. thanks a lot !!

Thanks Daniel! but it seems that grasshopper file needs a geometry as input. right? because when I run the file I do not get any curve in it.
