TORSION
A two-way, thin, lightweight frame with a top
and bottom skin. A torsion frame allows for a
long span, while the skin acts as a diaphragm
that keeps the frame rigid. The One to Several
Table’s tabletop utilizes a torsion structure
(modified, as it has only one skin rather than
two). The tabletop serves as a top skin that
keeps the frame beneath square and rigid.
Combined, the skin and frame afford a large
expansive table that is both lightweight and
stable.

VIERENDEEL
An orthogonal frame with vertical, parallel
members that are fixed at the top and bot-
tom. A Vierendeel structure offers a light-
weight rigid frame with rectangular space
between members, which can handle a very
long span. The Open Cabinet is formed by a
Vierendeel frame, with shelves that are
actually secondary elements. The Open Cabi-
net’s dividers and outer cabinet form the
lightweight Vierendeel structure that can
carry significant weight and handle a long
span.
