1. 2.Vaulted structures

   • Vaulted structures are formed by arches and vaults using stones that are cut in such a way that the only stress they support is compresion.

2. 8.Spatial and geodesic structures

   • These are three-dimensional structure bars, which combine the properties of vaults with triangulated structures to create curved shapes and cover large spaces.

3. 7.Pneumatic structures

   • Pneumatic structures are light and easy to transport, set up and dismantle

4. 1.Massive structures and lintels

   • The first man-made structures were carved from a rock or were built by stacking rocks or other materials.
     • Stack: A group of pile of material placed on on top of another.
   • Short stone or wooden lintels were also used to make windows and open spaces.
     • Lintel: A horizontal support across the top of two vertical posts or columns.

5. 4.Suspended structures

   • This type of structure uses cables, called suspenders which the structure hangs from. Cables are used to fasten bridges, marquees, antennas and towers.

6. 6.Laminated structures

   • These are formed by laminates of metal, plastic or composite material like reinforced concrete. Their curved shape and folds give them their strength.

7. 5.Reinforced concrete structures

   • The structure concrete resist with a steel rebar frameworks it can also bear traction. For columns, slabs, foundations...

8. 3.Triangular structures

   • These structures are made from bars, normaly metal or wooden. The use for triangular shapes means they are not easily deformed.
