Man made structures

Man made structures

1. Laminated structures

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

2. Reinforced concrets structures

   • Concrect led to major advances in construction because it could be made into any shape.Concrete resists compression and with steel rebar fameworks it can also bear traction

3. Suspended structures

   • This type of structures used cables called suspenders which the structure hangs from.When they can be ajusted,they are called tension members

4. Triangular structures

   • These structures are made from bars,metal or wooden

5. Vaulted structures

   • Are formed by arches and vaults using stones that are cut .The romans used to build bridges

6. Massive structures and lintels

   • Strack: A group or pile of materials placed one on top of another Lintel: A horizontal support across the top of two vertical parts or colums
   • Man made structures 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 (In grece temples)

7. Over time human beings have became better at building structures.We know more about them and we have lighter and stronger materials
