Geometrically Nonlinear Structures – or why it is good to be a lightweight

Event Description

Apart from the weight, there is nothing lightweight about lightweight structures. With traditional structures the loads are resisted by stiffness in beams, columns, and walls; with tension-only and compression-only structures the overall form of the structure becomes crucial. Get it right and the structure can span huge distances with minimal material; but get it wrong and you are in trouble.

Traditional structures are linear, stiff, restricted, heavy, and inefficient. Lightweight structures, on the other hand, whether in fabric, cable, timber, concrete, or stone, are nonlinear, long spanning, flexible, highly efficient, and environmentally friendly.

When form follows force as well as function, the result is a structure that soars.
