Cantilevers, Design + Structure

Cantilevers Cantilevers Cantilevers...
Since I'm doing a cantilevering structure,
I look into long and slender cantilevers for my design and after much research I came across a hummingbird.















I'm intrigued by the hummingbirds structure, and it's body and beak ratio.
I understand that simply scaling up the structure will not result into a structurally stable design on an architectural scale. However, with further investigation I think it is plausible to use the hummingbird skull+beak formation to develop my overall design.

For the Steel Structure I will look into and investigate the structure of plant stems. Experiments have shown that hollow stems are remarkably light yet very strong, which is an important component of a cantilevered structure. The transverse septa at nodes in stems play a vital mechanical role-they resist cross-sectional rupturing when sterns are bent.



Structures such as the tree fern stem shown at left, lack any form of major mechanical supporting tissues but is based on a series of Inverted 'V' - shaped fiber caps, delimiting the central hollow from the otherwise fibrous stem. These trees are capable of growing to up to 20-30 meters tall.

The stem of Equisetum shown above is an example of a non-woody species, but hollow-centered, adding strength to the structure

As for model and renders....I'll post that later...
