Structure

Structure

1. Are

   • The set of elements of an object or body that support external actions so that the objet or body doesn't deform or break
     • And whose
       • Functions
         • Are
           • Bear weigths
           • Serve as protection
           • Keeping fit
           • Resist external force

2. Are subject to

   • Forces
     • Are defined as
       • Anything that can deform a body or make it move or stop.
         • Loads
           • Could be
             • Permanent loads
               • These don't move over time
                 • Effort
                   • Is the internal force than an object experiences when we apply one or more forces.
                     • Could be
                       • Tension
                         • We produce tension when the forces stretch the object they're acting on.
                       • Compression
                         • We see this force when we try to crush or compress an object.
                       • Bending
                         • This is when forces try to bend the body they act on.
                       • Torsion
                         • In this case the forces try to twist the body they act on.
                       • Cutting
                         • This force tries to divide the object at a specific point.
             • Variable loads
               • These sometimes affect the object and sometimes they don't

3. Conditions

   • Stability
     • It must remain upright and not fall over to do this a structure's centre of gravity must be in the centre of it's base
       • To make the structure more stability
         • Make the base wider
         • Bury the bottom part in the ground and use a special foundations
         • Centre he weight of the ibject at the bottom. We can even add extra weight artificially.
         • Fix the structure to the ground
   • Resistance
     • It must be able to bear the ensions acting on it without breaking
   • Rigidity
     • Althougt all object deform slightly when a force acts on them, this deformation must not prevent the structure from performing is function
       • To give more rigidity
         • Comprension
           • We use thick elements, with the same amount of material and preferably hollow to avoid bending
         • Tension
           • We give a structure more regidity and resistence by increasing the quantety of material in the element
         • Bending
           • We have to increase the edges of the elements and put more material on the top or bottom part of the elements
         • Weld
       • Shape
       • Joints
       • Triangulation
