MAN MADE STRUCTURES

MAN MADE STRUCTURES

1. Massive st and lintels

   • The first Man-made structure was made by pilling rocks and other materials. To make windows and open spaces they used short stones and wooden lintels

2. Vaulted st

   • Are formed by arches and vaults using stones that ate cut in a such way that the only stress can support is compression

3. Triangular st

   • These Structures are made of bars, wood or metal. They are not easily deformed, This idea is very esencial for bridges with large trusses or some structures.

4. Suspended st

   • Suspenders are cables, when they are adjusted they are called tension members, the cables they only bear traction stress and they can adapt their shape to different loads.

5. Reinforced concrete st

   • The concrete has helped a lot in the constructions since you can make any shape with it and it can also bear traction. It's a very strong material which is used in all types of buildings. Under the floor there are slabs: small beams called joists. The columns don't sit directly on the ground because they would sink so they put a fundations which spread out the weight and it's load.

6. Laminated st

   • These are formed by laminates of metal, plastic or composite material like reinforced concrete. Their curved shape and folds give them straight and they bear the stress of traction and compression on the surface

7. Pneumatic st

   • They are light and easy transport set up and dismantle, We use them on constructions like field hospitals or funfair atracctions for children. They use compressed air inside. This makes stay upright.

8. Spatial and geodesic

   • These are three-dimensional structures of bars, which combines the properties of vault and triangulated structures to created curves shapes and cover large spaces.
