STRUCTURES

STRUCTURES

1. Set of elements that allow to mantain it shape and size

   • Types of structures
     • Natural
       • The queleto of the animals ,
     • Artificial
       • Support weights , to resist external forces , to mantain the form and protecting objects
   • Loads and efforts
     • Static load
       • Act permanently on a structure cemeur ...
     • Dynamic load
       • Not acting constantly on the structure wind , snow...
     • Traction: forces try to strech the body on wich they act
       • Flexion try to bend the element on wich they are applied
         • Torsion: try to twist the element wich they act
           • Cuting: act like two edges at a scissors
             • Compression: forces try to strech the body
   • Elements of a structure
     • Viga: horizontal element that support bending , traction and compression efforts
       • Pilar or column: vertical element that supports compressive and bending stresses
         • Foundation: base of the column
           • Tirante: element that supports traction efforts
             • Square: can withstand tensile or compressive stresses
               • Resistance
                 • Is asociated with the way in wich the elements of it are designed
               • Stability
                 • Position with the gravity center of a body
