    • STRUCTURES
    • INDEX
      • Structures
      • Types of structures
      • Structural elements
      • Types of unions
      • Forces on structural elements.
    • STRUCTURES
      • A structure is a group of elements somehow united to support a load with stability.
      • Everything has a structure, otherwise it would colapse under the force of gravity, the force of wind, or any other force.
      • Examples: Humans----->skeletons
      • Bicycles---->frame
      • Houses----->columns, beans and roof.
    • TYPES OF STRUCTURES: FRAME
      • Is the common choice of structures.
      • Are compose of long elements, join to each other(bars and tubes).
      • Are made of strong materials.
      • They are easy to buy and build, they don't require much material, but they are expensive to manufacture.
    • FRAME STRUCTURES
    • TYPES OF STRUCTURES: SHELL
      • Are made of a thin outer layer material.
      • They are like a strong and hard coat that maintains the required shape.
      • Examples: cardboard boxes, bottles, cars, eggs and airplanes.
    • TYPES OF STRUCTURES: ARCH
      • There are many types, but the semicircular arch still remain the most used.
      • Free spaces is left under the arch, consequently rivers, streams or other obstacle can pass down it.
    • MIX AND MATCH
      • Sometimes different types of structures are combined in one.
    • TYPES OF STRUCTURES: MASS
      • They are simply made of clump material filling the body completly.
      • Low cuality material are used.
      • Natural examples: Mountains or coral reefs.
      • Manmade examples: Dams or load bearing walls.
    • TYPES OF STRUCTURES: SUSPENSION
      • A suspension structures hold an element by cables that are held from the top of a tall comlumn.
      • The space between one colum and the next is call the spam. Suspension strctures have the longest spam of all strcutures.
    • STRUCTURAL ELEMENTS
      • Element: The simplest part of the whole.
      • The forces for every element are calculated, and the elements is designed to withstand them.
      • The parts of an structural element are fundations, columns, beans and primary beans.
    • TYPES OF UNIONS
      • They must be united.
      • Structural elements must be somehow united to the other elements of the structure.
      • Unions classified into::
      • Permanent unions :they dont need to be desassembled.
      • Non-permanent unions :they are designed to be assembled and disassembled when needed.
    • FORCES ON STRUCTURAL ELEMENTS
      • Each of the elements in an structure will withstand a particular force which is a result fo the load that it is supporting.
      • There are five types of forces on structural elements:
      • Censional strain
      • Compression forces
      • Shear strain
      • Torsion forces
      • Bending forces
    • TENSIONAL STRAIN
      • It is caused by forces that pull an element from its ends and starts.
    • COMPRESION FORCES
      • Is caused by squeezed or buckled an element
      • When you squeeze an element it becomes shoter and thicker.
    • SHEAR STRAIN
      • It is caused byact across a material in such a way that they can force one part of an element to slide over another.
    • TORSION FORCES
      • It is caused by applying a force in one of the ends and suppot the other end, the element will twist.
    • BENDING FORCES
      • It is caused by applying a force on the middle of the element an suppot the ends.
    • LOCAL STRUCTURES

    • INTERNATIONAL STRUCTURES
        Giza piramids Kio towers
