structures

1. A structure is a set of elements of an object that allows it to maintain its shape and size without deforming when forces act on it.

   • TYPES
     • NATURAL STRUCTURES
     • ARTIFICIAL STRUCTURES
   • FUNTIONS
     • SUPPORT WEIIGHTS
     • TO RESIST EXTERNAL FORCES
     • PROTECTING OBJECTS
     • TO MAINTAIN THE FORM
   • LOADS
     • DYNAMIC LOADS
       • Are those that do not act in a constant way of the structure, like the rain, the wind...
     • STATIC LOADS
       • Are those that act permanently on a structure, like the weight of the structure.
     • PROPERTIES
       • STABILITY
         • Is associate with the position of the gravity center of the center of a body. The center of gravity is the point where all the weight of an object is concentrated.
       • RESISTANCE
         • Is associate with the way in which the element of it are designed. The triangle is the best form to make a structure resistance.
   • EFORTS
     • TRACTION
       • It occurs when forces try to strech the body on which they act.
     • COMPRESSION
       • Occurs when the forces try to strech the body.
     • FLEXIOM
       • The forces tr to bend the element on which they are applied.
     • TORSION
       • The forces try to twist the element on which they act.
     • SHEARING OR CUTTING
       • The forces act like the two edges of a scissors.: very close together, one up and one down, trying to cut the object.
   • STRUCTURES
   • ELEMENTS
     • VIGA
       • Is the horizontal part that support bending, traction and compression effots.
     • PILAR
       • Is the vertical part that support bending stresses.
     • FOUNDATION
       • Is the base of the column and that carries compressive stresses.
     • TIRANTE
       • Is the element that support traction efforts.
     • SQUARE
       • Is the element that can stand with tensile or compressive stresses (depending on the case)
