Complex Structures

I’m not sure why, but I have randomly gotten the urge to learn more about complex structures…

The Geodesic Dome and Bucky’s ideas of tension and compression are great, but does anyone have any more resources (books, websites, etc) on these and other types of structural design principles?

There are a slew of Architectural and Structural Engineering books out there, and it is difficult to sift through them and find one that fits my (probably fleeting) interest. Any ideas would be great!
