Roof Structures using Cables

Roof Structures using Cables

(OP)
Hi everyone:

I'm struggling with the design of a green roof made with cables (or a doubly curved cable net). Specifically with the analysis.
It's a complex structure using cables with double curvature similar to the Sydney's Aurora Place (see image)

Does anyone know a software or approximate method I can use to determine the design tension?

JMC,

RE: Roof Structures using Cables

I had done a proposal about 45 years ago using a cable structure. There was a lot of analytical information at the time; it was trendy. Fellow that had been involved mostly was Frei Otto... Even US Cable had a design manual. You may start there for some background.

Yes, it's been sitting on my pile of "I'll get to it someday", but I picked up the USS "Design Fundamentals of Cable Roof Structures" for a few bucks

Yup... was USS...
Thanks, Dik

I stumbled upon the following software developer a few months ago when looking for tensile structures:

I think that Oasys GSA also has some tensile surface analysis features:
