  • STRUCTURE
  • INDEX
    • TYPE OF STRUCTURES: (Frame, mass, shell, mix and match...)
    • STRUCTURALS ELEMENTS.
    • TYPES OF UNIONS: Permanent and non-pernanent unions.
    • FORCES ON STRUCTURAL ELEMENTS : ( tension strain compression forces shear strain... )
    • INTERNATIONAL AND NATIONAL STRUCTURES.
  • FRAME STRUCTURES
    • Frame structure is composed of long elements joined to each other. The space between them is empty,bicycles, sawhorse for example.
  • SHELL STRUCTURE
    • 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.
  • ARCH ᄎ
    • It was inveted by romans.
    • The most important stone was called “keystone”.
  • MIX AND MATCH
    • It is a combination of differents structures witch made up a more complex one.
    mix and match
  • MASS
    • They are made up of low-quality materials.
    • There are two types: Natural and man- made structures.
    • They have adventages(Held in place by its own weight) disadventage(need much material).
  • SUSPENSION
    • It holds an element by cables.
    • Space between the two coloums is called “spam”
    • Advetages:Good for covering large spans.
    • Disadventage:The price
  • STRUCTURAL ELEMENTS
    • It is the simplest part of the whole.
    • Foundation:An element joined to the ground and to the column.
    • Column:Is joined to the primary beans.
  • TYPES OF UNIONS
    • Permanent unions:They are meant for structure that won' t need to be disassembled.
    • Non-permanent unions: They are those designed to assemble and disassembled the element of the structure.
  • TYPES OF FORCES ON STRUCTURAL ELEMENTS
    • TENSIONAL STRAIN
    • COMPRESSIONS FORCES
    • SHEAR STRAIN
    • TORSION FORCES
    • BENDING FORCES
  • TENSIONAL STRAIN
    • It is the strain that causes an element to stretch it can be doe to forces that pull an element from its ends.
  • COMPRESSION FORCES
    • They are forces which causes an element to get squeezed or buckled.
  • SHEAR STRAIN
    • They act across a material in such a way that they can force one parte of an element to slide over another.
  • TORSION FORCES
    • If you apply a turning force(called ”torque”)at a end of an element and, if
    • the element is fixed to a suppe at the other end,the element twists.
  • BENDING FORCES
    • They act at an angle to a member making it bend.
  • LOCAL STRUCTURE
  • INTERNATIONAL STRUCTURES
