Truss Optimisation App 3

Thought I would share this neat, little LayOpt app that is based upon the Grasshopper plugin Peregrine.

You can load heaps of different examples including the Mitchell truss. Set other boundary conditions, loads and optimisation constraints.

This layout optimisation was used recently for a transfer truss on a hotel project in London.





 
That's a fun toy. Thanks, Trenno!
 
How does it work? Does it consider buckling failure of compression elements when determining efficiency, or just assume some yield strength of material and only consider yield failure?
 
nice find...should make the strut and tie discussions on here more colorful.

Its a really cool toy. I just think the fabrication costs of such “optimized” systems would be ridiculous. Materials are cheap, men are expensive.

 
Johnie - we're talking about vastly different things here.

Canwesteng - I believe the proper Peregrine app and their other software does consider Euler buckling. However this web app seems to be stress limit based.

MIStructE_IRE - They are focusing on this using their simplication/rationalisation routines. From what I understand that hotel example did come out to be cheaper overall. Link to original IStructE article here.

 
I wonder if this will save Kookt some time drawing out his S&T models!

It seems likely to me that in the years and decades to come, 3d printing, combined with such optimization systems (which could get enhanced by deep learning type algorithms) will be increasingly used. I would expect that advancements in 3d printing technology for the construction sector will steadily reduce the fabrication cost problem.
 
You’re right there Eagleee. That will certainly happen I think, even in the relatively near future.

I’d really love to be around to see structural engineering in a couple of hundred years time. Can you imagine the possibilities!

You can get a robot to do your job today. Put it at your desk and get it to repeatedly hit its head on desk, that's about 75% of my day sorted checking others work.... [banghead]
