Diagrid buildings
In tall buildings construction, the state-of-the art load bearing design concept is called diagrid.

The World's first diagrid hyperboloid structure was the "Shukhov tower" in Polibino, designed in 1896 by Russian engineer and architect Vladimir Shukhov.

These structures are very resistant, even to the pass of time.

The key of diagrid structures are the nodes, they transmit the forces between the diagonal members and the horizontal rings. They can be fabricated by bolting, welding, using concrete, or any combination of them.
