structures

structures

1. efforts and deformations

   • compression
     • 2 forces looking to each other (pointing inside the object and reducing its length
   • tension
     • 2 forces looking out of the objecta and expanding it
   • bending
     • one force in the middle of a long element pointing in 90º
     • 2 rotations in the extremes looking inside the object
   • shear
   • torsion

2. massive structure

   • it is built using big block with a lot of material, it is heavy

3. frame

   • it is built using vertical elements (columns or pilar= and horizontal elements (beams)

4. truss or triangular

   • it is built using rigid elements (bars) forming trinagles

5. shell

   • its supportin element is placed in the external surface and it thin

6. suspended

   • it is being supported by wires and ropes that work in tension

7. pneumatic

   • it is beeing supported by air presure
