1. What is a structure?

   • A structure is the set of elements in a body that resist the forces that act on it (loads), fulfilling three conditions:
     • 3 Conditions
       • remaining upright (stability). without breaking (resistance). without deforming too much (rigidity).

2. types

   • massive
     • pyramid, stone bench, etc
   • vaulted
     • stone bridges, cathedrals, arches,
   • suspended
     • suspended bridges
   • lattice
     • Truss (cerchas). Joists (viguetas). Beams (vigas) Pillars (pilares); columns (columnas). Foundations (cimientos)

3. Loads

   • The forces that act on a structure are called loads. Loads can be permanent or variable

4. stress

   • Each element of a structure is subjected to stress (internal tension). The stress is proportional to the force applied and inversely proportional to the element section surface.
