   • STRENGTH: ability to withstand external forces without breaking.

2. TYPES

   • Mass structures
   • Frame structures
   • Truss structures
   • Suspended structures

3. CONDITIONS FOR STRONG STRUCTURES

   • Rigidity
     • ELEMENTS TO INCREASE RIGIDITY
       • Trussing
       • Brace
       • Stay cables
       • Sections
         • open sections
         • closed sections
   • Equilibrium
     • stable
     • unstable
   • Stability
     • ELEMENTS TO INCREASE STABILITY
       • widening the base
       • weight at a low point
       • using foundation or anchors
       • supporting with stay cables

4. TYPES OF STRESS

   • Compression
   • Tension
   • Bending
   • Torsion
   • Shear
