MAN MADE STRUCTURES

MAN MADE STRUCTURES

1. VAULTED

   • Formed by arches and vaults using stones that are cut in such a way that only stress they support is compression.

2. TRIANGULAR

   • Made from bars, normally metal or wooden. Use of triangular shapes, they are not easy deformed. Ideal for building bridges, covered with large trusses and vertical structures.

3. SUSPENDED

   • Uses cables (suspenders). They can be adjusted (tension members). Only bear traction stress. Cables are used to fasten bridges, marquees, antennas and towers.

4. REINFORCED CONCRETE

   • Led to major advances in construction, it could be made into any shape. Resist compression and with steel rebar. It is strong material, used in all types of buildings
   • Slabs
   • Joists
   • Beams
   • Columns
   • Fundations

5. LAMINATED

   • Formed laminates metal and plastics. Curved shape and folds. Bear the stress of traction and compression. Ribs give rigidity in exact points.

6. PNEUMATIC

   • Light and easy to transport, set up, and dismantle. Stay upright.

7. SPATIAL AND GEODESIC

   • 3 dimensional structures of bars, which combine the properties of vaults with triangulated structures.

8. MASSIVE

   • Were carved from rock or were built by stacking rocks or other materials. Short stone or wooden lintels were also used to make windows and open spaces.
