Tensegrity Solutions Assembles Tensegrity Obelisk

SHIRLEY, MA -- Tensegrity Solutions completed assembly of a tensegrity obelisk on June 25, 1998. It serves as a free-standing garden trellis on which morning glories, scarlet runner beans and possibly thunbergia will be grown. The obelisk is composed of twelve 4-foot (1.22 m) struts arranged in four layers using a zig-zag design. It has triangular ends, the apex triangle having a side length of 19.2 inches (.488 m), the base triangle having a side length double that. It is approximately 9 feet (2.7 m) tall. It is dedicated to Robert W. Burkhardt, Sr., a distant relative of the principal of Tensegrity Solutions.

Background information on zig-zag implementations of tensegrity technology can be found in Anthony Pugh's book An Introduction to Tensegrity (University of California Press, 1976).

Photographs of the assembled structure can be found at http://www.trip.net/~bobwb/ts/tenseg/obelisk/photos/index.htm.

An alternative diamond version of the structure was explored, and although stiffer, the layout of the struts and tendons seemed less suited to the trellis application.

The diamond version of the obelisk is a variation on structures Kenneth Snelson has designed. He calls his realizations towers. The following are links to photos of two of those structures:

Needle Tower (Hirshhorn Museum, Washington, DC)
Equilateral Quivering Tower
