Transcript

  • 1. STRUCTURES AND FORCES
  • 2. TYPES OF STRUCTURES • Frame Structures • Shell Structures • Arch Structures • Mix and Match • Mass Structures • Suspension Structures
  • 3. FRAME STRUCTURES <ul><li>Is the most common choice of structures.
  • 4. These structures are composed of long elements. </li></ul>
  • 5. SHELL STRUCTURES <ul><li>Are made of a thin outer layer.
  • 6. They are like a strong and hard coat that maintains the require shape </li></ul>
  • 7. ARCH STRUCTURES <ul><li>The Romans invented the arch.
  • 8. The stone at the very top is called the keystone </li></ul>
  • 9. MIX AND MATCH <ul><li>Different types of structures are combined </li></ul><ul><li>The combination is a moree complex structure. </li></ul>
  • 10. MASS STRUCTURES <ul><li>They are made of low quality of materials.
  • 11. The structure is normally thick.
  • 12. Advantage: Held in place by its own weight.
  • 13. Disadvantage : Heavy need much material. </li></ul>
  • 14. SUSPENSION STRUCTURES <ul><li>A suspension structure holds an element.
  • 15. Are often best for bridges.
  • 16. Good for covering a very large span. </li></ul>
  • 17. TYPES OF UNIONS <ul><li>PERMANENT UNIONS :
  • 18. They are meant for structures that will not needed to be disassembled.
  • 19. Welding, rivets, glue... </li></ul><ul><li>NON-PERMANENT UNIONS :
  • 20. Are those designed to assemble and disassemble the element of structures .
  • 21. Nuts, bolts, clamps, friction... </li></ul>
  • 22. FORCES ON STRUCTURAL ELEMENTS <ul><li>Tensional strain
  • 23. Compression forces
  • 24. Shear strain
  • 25. Torsion forces
  • 26. Bending forces </li></ul>
  • 27. TENSIONAL STRAIN <ul><li>Is the strain that causes an element to stretch
  • 28. It can be due to forces </li></ul>
  • 29. COMPRESSION FORCES <ul><li>They are those forces which causes an element to get squeezed or buckled </li></ul>
  • 30. SHEAR STRAIN <ul><li>Shear forces act across a material in such a way they can force.
  • 31. A good example are when we cut with the scissors </li></ul>
  • 32. TORSION FORCES <ul><li>If we apply a turning force called torque at one end of an element and, if the element is fixed to a support at the other end the element twists </li></ul>
  • 33. BENDING FORCES <ul><li>Act at an angle to a member making it bend </li></ul>
  • 34. BY: Manuel Folgado and Ramón Barrabés
