Man made structures

1. Massive structures and lintels

   • The first man made structures
     • This are made of stone or wooden lintels
       • For example:Greek temples

2. Vaulted structures

   • These structures are made by the Romans
     • Are made of stones
       • For example:bridges and cathedrals

3. Triangular structures

   • These structures are made from bars,normally metal or wooden.
     • The use of triangular shapes means they are not easily deformed
       • For example:The Eiffel Tower

4. Suspended structures

   • This type of structure uses cables,called suspenders
     • They don t need columns.
       • For example:The brideges of today

     • They use triangles and tetrahedrons,because these shapes cannot be easily deformed
       • For example:Geodesic dome

   • Are made of concrete and steel rebar
     • And these structures can resist compression and traction
       • For example:The structure of a building or a structure of a ceiling
