MAN-MADE STRUCTURES

MAN-MADE STRUCTURES

1. massive structures

   • were built by staking rocks or other materials. This left lttles space between them

2. vaulted structures

   • are formed by arches and vaults of stone. The soport is compression

3. triangular structures

   • Are made from bars normally metal or wooden. These use to triangular shapes means they are not easily deformed

4. suspended structures

   • This use cables called suspenders. When they can be adjusted they are called tension members.The cables only bear traction strees

5. rainforce concrete structures

   • concrete led to major advances in constructions. Concrete resist compresion and with steel rebar

6. laminated structures

   • They are formed by laminates of metal or composite mterials. Their curved shape and folds give them their strength

7. pneumatic structures

   • Are light and easy to transport these structures use compresed air inside them. When they expand they stretch the outer plastic surface

8. Spatial and geodesic

   • These are three-dimensional structures of bars which combine the properties of vaults with triangule structures to create curved shapes
