MAN MADE STRUCTURES

MAN MADE STRUCTURES

1. MASSIVE STRUCTURES AND LINTELS

   • The first man-made structures were carved from rock or were built by stacking.
   • LINTELS
     • Were also used to make windows and open spaces,for example, in greek temples 
   • STACKING
     • This was the first type of man made structures 

2. VAULTED STRUCTURES

   • Are formed by arches and vault using stones that are cut in such a way that the only stress they support is compression.

   • VAULTS

3. TRIANGULAR STRUCTURES

   • These structures are formed by bars,normally metal or wooden. 
   • TRUSSES
     • Triangular structures are covered by trusses 
   • SCAFFOLDS
     • And vertical structures like scaffolds 

4. SUSPENDED STRUCTURES

   • This type of  structure uses cables, called suspenders wich the structures  hangs 
   • SUSPENDERS
   • MARQUEES
   • TENSION MEMBERS
   • This type of structure uses cables, called suspenders wich the structures hangs

5. REINFORCED CONCRETE STRUCTURES

   • Concrete led to major advances because it could be made into any shape  
   • SLABS
     • There are under the floor

   • JOISTS
     • Small beams
   • BEEMS
     • They transfer your weight

   • COLUMNS

6. LAMINATED STRUCTURES

   • These are formed by laminates of metal, plastic or composite material like reinforced concrete 
   • RIBS
     • Give rigity in exact points

7. PNEUMATIC STRUCTURES

   • Pneumatic structures are light and easy to transport set up and dismantle.For this reason, we use them in constructions like field hospitals or funfair attractions for children

8. SPATIC AND GEODESIC

   • These are three-dimension structures or bars
