  • Structures
    • A structure is a group of elements somehow united to support a load with stability
    • Frame estructures
    • Shell structures
    • Arch
    • Mass structures
    • Suspension structures
  • Frame structures
    • Is the most common structure.
    • They are composed of long elements joined each other.The elements are made up of strong materials
  • Shell Structures
    • Are made of a thin outer layer of material.These volumen can be empty or can be filled with something.
  • Arch
    • Romans invented the arch.
    • Are many types,but semicircular arch is the most used.
    • The stone at the top is called 'keystone'
  • Mass Structure
    • Are simply made of clump material and with a low-quality
    • It is normaly thick
    • Mountains and corals reefs are natural examples
  • Suspension structures
    • It holds an element by cables that are held from the top of a tall column
    • The space betwen two columns is called span
  • Structural elements
    • It is the simplest part of the whole
    • In a structure, the forces for every elements are calculated and the element is designed to withstand them.
    • The structural elements are:
    • foundations joined to columns and primary and secondary beams
  • Types of unions
    • Unions are use to unite elements there are two types:
    • Permanent unions:structures not need to be disassembled
    • Non-permanent unions:elements can be disassemble and assembled
  • Forces on structural elements
    • A successful structure must be able to withstandall the forces that it will experience without toppling over or collaping
  • Types of forces
    • Transional strain
    • Comprenssion forces
    • Shear strain
    • Torsion forces
    • Bending forces
    • The strain that causes an element to strench
    • It can be due two forces that pull that pull an element from its ends
      Transional strain
    • Comprenssion forces
    • They are those forces wich cause an element to get squeezed or buckled
    • Shear strain
    • Sher forces act across a material in such a way that they can force an element to slide over another
    • Torsion forces
    • If you apply a turning force aione end of an element and , if the element is fixed to support at the other end, the element twists
  • Bending forces
    • Act at an angle to a member making it bend
