Bucky Fuller's Geodesic Domes-housing all NATO spying Radars, The St.Louis Arch, the steel frame of my Wonderchair(0.8Kg steel+1.Kg Bamboo)--these are created out of education, observation, inspiration coupled to the fundamentals of strength of materials which we all are taught in 1st year at engineering college.
There are unimaginative designs like 37000 Ton First Howrah Bridge, the Xoraight Bridge+ most Indian Rail Bridges ,the better imaginative ones - like 2nd Howrah Bridge-~3000 Tons, and the still better ones like the Denmark-Sweden Undersea/oversea railbridge. You will find synthesis of poetry/philosophy/matematics/aesthetics/analysis in millions of designs that are snowballing every day in the fields of money-driven
GPS/Cellphones/Satellites/Laser-meditronics.
But do not forget about Nature's own designs-- the brain, the bamboo( ideal L/r ratio), El-Nino....
Actually the Structural Problem is more likely solved by a team of Post-doctoral research team at Princeton aided by a fleet of Supercomputers--not by a so-called Structural Designer-more likely to be a "Mitti Khodow Gitti Dalo" half-engineer.

This is nothing new really. Architects often design arbitrary forms ( and why not?) and then manufacture justifications for it,sometimes tenuous, sometimes plausible, in order to answer to the crowd short on imagination.Forms of nature have, throughout the ages, provided inspiration and ideas, for structural and architectural creations. Take the case of the leaf of a finger palm ( tokou) -- how the fingers of the leaves ( v-shaped in profile) inspired folded plate configuration for construction. The massive cantilever of the stem that withstands enormous stresses created by wind on the grossly disproportionate leaf surfaces -- is a study in itself.Bucky Fuller's geodesic dome concept was inspired by cell structures in nature.Most shapes that inspired architecture and structure in the man-built environment however are geometric in nature. Reason being the limitation of construction materials and systems. Amoebic forms could not be economically justified easily due to such limitations. But once one can jump that constraint, of economy, one hardly requires any tortured ( or architortured) rationale tomanufacture and wave.At 10:46 AM -0700 8/21/06, Dilip/Dil Deka wrote:Replicating the shape of cells to make it an architectural feature is one thing but studying the structural concept of nature's creation (cells) and using it to produce simple and strong structures is something else.Have structural engineers thought about it?

RovnerArchitects sometimes turn to nature for inspiration, but their focus is generally on the macroscopic scale. The designers of a building that will house the new Institute for Nanobiomedical Technology & Membrane Biology in Chengdu, China, have turned instead to the microscopic scale: The building will incorporate many features inspired by cells.COURTESY OF SLOAN KULPER
Biohaus Bulges protruding from the surface of the cell-shaped building are meeting areas designed to resemble proteins embedded in a membrane (top). The interior features a garden with pools shaped like mitochondria (middle) and an atrium with bridges representing X and Y chromosomes (bottom).Meeting areas whose windowed exterior walls bulge from the surface of the cell-shaped building will represent proteins in a cell membrane. An interior garden will include pools shaped like mitochondria and other organelles. And the building will contain a crystal-shaped lecture hall whose ceiling lights will be arranged in the crystal diffraction pattern of a protein. Construction of the $12 million building, which will include many other cell-like attributes, will start in 2007 or 2008 and will likely be completed by 2009.The design is the fruit of a collaboration between Shuguang Zhang, associate director of the Center for Biomedical Engineering at Massachusetts Institute of Technology; MIT graduates Sloan Kulper and Audrey Roy; and architects at Tsinghua University. Zhang is founding adviser for the Chinese institute, which will be based at Sichuan University, where he earned an undergraduate degree in biochemistry.Kulper was majoring in architecture at MIT when he took Zhang's course on the molecular structure of biological materials, which highlighted the parallels between architecture and biological structures. After Zhang became involved in the Chinese project, he sent Kulper and Royat the time a computer science and electrical engineering majorto Beijing for three months to collaborate with the Tsinghua University architects. "We worked with images of proteins, membranes, and organelles alongside photos and textbook images of glazing systems and cantilevers," Kulper recalls."Nature has produced abundant magnificent, intricate, and fine molecular and cellular structures," Zhang says. "If they can be amplified billions of times, as in a building, then these structures can be seen, touched, and admired. At that large scale, they can also be very educational." He hopes that this "first molecular bio-architectural design" will stimulate the creation of other buildings based on biological structures.
