STRUCTURES

STRUCTURES

1. HAS TO FULFILL CONDITIONS

   • STABILITY
     • Remaining upright and not tip over
     • CENTER OF GRAVITY
       • SHOULD BE CENTRED OVER THE BASE AND CLOSE TO THE GROUND
   • RESISTANCE
     • To bear loads without breaking
     • Other material
     • MORE MATERIAL
     • OTHER SHAPE
   • RIGIDITY
     • TRIANGULATION
       • To avoid deformation os articulated structures we use triangulation: One diagonal bar (suports traction and compression) Two diagonal Ropes (supports only traction) 

2. TYPES

   • Massive
   • Vaulted
   • Lattice
   • Suspended

3. RESIST FORCES

   • A body doesn't move when in force equilibrium
   • LOADS
     • VARIABLES
     • PERMANENT
     • STRESSES
       • The stress is proportional to the force applied and inversely proportional to the element section surface
       • TENSION
       • COMPRESSION
       • BENDING
         • Combination of tension and compression Reinforced concrete beams traction is supported by steel bars
       • SHEAR (CUTTING)
       • TORSION
