Transcript

  • 1. Structures
  • 2.
    • A structure is group of elements somehow united to support a load with stability.
  • 3. Frame Structures
    • The frame structure is the most common choice of structure. This structures are composed of long elements joined to each other at the end. The elements of frame structure are made of strong materials
  • 4. Mix and Match
    • It is a combination of differents structures witch made up a more complex one. For example: houses have brick walls.
  • 5.  
  • 6. Arch
    • It was invented by the Romans. Its own weight is the main load and the geometry of the arch desplaces the forces to the sides
  • 7. Shell structures
    • A shell structure is one in which the strength reloads into the outer surface.
  • 8. Compression Structures
    • A body is subject to force of compression when two opposing forces are applied and these forces have the tendecy to flatten the body .
  • 9. Bending Structures
    • A body is subject to a bending force when it receives one or more forces that have the tendency to bend it.
  • 10. A example of bending structure:
    • A book case: If
    • we place a great
    • dealof weight on a
    • shelf in a bookcase
    • it changes shape owing
    • tothe force of bending.
  • 11. Tension structure
    • A body is sunject to force of tension when two opposing forces are applied and the forces have the tendency to lengthen the body.
  • 12. Example of tension structure:
    • Many modern bridges use thick steel cables to hold up the bridge platform over which the cars drive.These cables are called suspension cables
  • 13. Shear Structures
    • A body is subject to a shear force when two opposing forces are applied to it which have the tendency to cut it.
  • 14. Example of Shear Structure:
    • Scissors:Manual cutting tools work throught the use of 2 pieces of sharpened metal.The material(fabric,paper,metal...) receives a shear force that it cannot withstand,and as a result it is cut
  • 15. Torsion structures
    • A body is sunject to the force of torsion when two opposing forces are applied that have the tendency to twist it.
  • 16. Example of Torsion Structure:
    • Screw:When we use a screw we are subjecting it to a force torsion. The result is that the screw has the tendency to twist .
