IB Design Technology Topic A3.2.1 Structures in Nature and the Built Environment Revision Notes (HL) | RevisionDojo

A structure is an arrangement of parts that carries loads and holds its shape

A structure is an arrangement of parts designed to support loads, withstand forces and keep its form and stability. Structures are everywhere: in the natural world of trees, bones and shells, and in the built world of buildings, bridges and furniture.

Note

Studying structures is really about how forces, materials and shape work together to create stable, functional designs.

Every structure must meet three demands:

Load-bearing: it carries weight, wind and pressure.
Stable: it holds its shape as conditions change.
Efficient: it uses as little material as possible for the strength it needs.

Nature builds structures that are light, strong and efficient

Shaped over time by evolution, each natural form squeezes several jobs (support, protection and growth) out of the same material.

Example

Honeycomb: a hexagonal pattern gives maximum strength from minimal wax.
Tree trunk: wide at the base and narrow at the top to resist bending under vertical loads.
Bird bones: hollow yet braced with internal struts, cutting weight for flight without losing strength.
Seashells: a spiral geometry and layered material resist compression and impact.
