     • There are made for rocks
       • The lintels were also used to make windows

2. Vaulted structures

     • Used to fasten bridges
       • Called tension members

5. Reinforced concrete structures

   • Concrete led to major structures
     • It is a very strong material
       • Can be used to build huge arches

6. Laminated structures

   • Are formed by laminates of metal
     • Their are curved
       • Give rigidity in exact points

7. Pneumatic structures

   • Are light
     • Easy to transport
       • Them stay upright
