  1. 1. STRUCTURE
  2. 2. INDEX <ul><li>TYPE OF STRUCTURES: (Frame, mass, shell, mix and match...)
  3. 3. STRUCTURALS ELEMENTS.
  4. 4. TYPES OF UNIONS: Permanent and non-pernanent unions.
  5. 5. FORCES ON STRUCTURAL ELEMENTS : ( tension strain compression forces shear strain... )
  6. 6. INTERNATIONAL AND NATIONAL STRUCTURES. </li></ul>
  7. 7. FRAME STRUCTURES <ul><li>Frame structure is composed of long elements joined to each other. The space between them is empty,bicycles, sawhorse for example. </li></ul>
  8. 8. SHELL STRUCTURE <ul><li>They are made of a thin outer layer sorrounde by a volume that can be empty or filled. Eggs, bottles, cars, ballons are examples of shell strucutures. </li></ul>
  9. 9. ARCH ᄎ <ul><li>It was inveted by romans.
  10. 10. The most important stone was called “keystone”. </li></ul>
  11. 11. MIX AND MATCH <ul><li>It is a combination of differents structures witch made up a more complex one. </li></ul>mix and match
  12. 12. MASS <ul><li>They are made up of low-quality materials.
  13. 13. There are two types: Natural and man- made structures.
  14. 14. They have adventages(Held in place by its own weight) disadventage(need much material). </li></ul>
  15. 15. SUSPENSION <ul><li>It holds an element by cables.
  16. 16. Space between the two coloums is called “spam”
  17. 17. Advetages:Good for covering large spans.
  18. 18. Disadventage:The price </li></ul>
  19. 19. STRUCTURAL ELEMENTS <ul><li>It is the simplest part of the whole.
  20. 20. Foundation:An element joined to the ground and to the column.
  21. 21. Column:Is joined to the primary beans. </li></ul>
  22. 22. TYPES OF UNIONS <ul><li>Permanent unions:They are meant for structure that won' t need to be disassembled. </li></ul><ul><li>Non-permanent unions: They are those designed to assemble and disassembled the element of the structure. </li></ul>
  23. 23. TYPES OF FORCES ON STRUCTURAL ELEMENTS <ul><li>TENSIONAL STRAIN
  24. 24. COMPRESSIONS FORCES
  25. 25. SHEAR STRAIN
  26. 26. TORSION FORCES
  27. 27. BENDING FORCES </li></ul>
  28. 28. TENSIONAL STRAIN <ul><li>It is the strain that causes an element to stretch it can be doe to forces that pull an element from its ends. </li></ul>
  29. 29. COMPRESSION FORCES <ul><li>They are forces which causes an element to get squeezed or buckled. </li></ul>
  30. 30. SHEAR STRAIN <ul><li>They act across a material in such a way that they can force one parte of an element to slide over another. </li></ul>
  31. 31. TORSION FORCES <ul><li>If you apply a turning force(called ”torque”)at a end of an element and, if
  32. 32. the element is fixed to a suppe at the other end,the element twists. </li></ul>
  33. 33. BENDING FORCES <ul><li>They act at an angle to a member making it bend. </li></ul>
  34. 34. LOCAL STRUCTURE
  35. 35. INTERNATIONAL STRUCTURES
