Classification of Structures

Importance of Structures

• Structures are essential in our world, designed for specific purposes.

Main Categories of Structures

1. Solid Structures

   • Uniform all the way through.
   • Strong from all angles.
   • Examples: Block of wood, brick, boulder, concrete wall.
   • Capable of supporting heavy loads.
   • E.g., Foundation of a building.

2. Frame Structures

   • Composed of a framework of beams, columns, and supports.
   • Components work together to bear the load.
   • Examples: Tall buildings, bridges, skyscrapers.
   • Steel framework carries the weight, allowing great heights.

3. Shell Structures

   • Thin and curved forms resembling hollow eggshells.
   • Curvature provides strength by distributing forces evenly.
   • Examples: Domes in sports stadiums, large pavilions, sports arena roofs.
   • Spans large areas with minimal material.

Classification Criteria

• Design: Understanding the design of the structure.
• Load-Bearing Method:
  • Solid: Uniform and solid all through.
  • Frame: Framework made of beams and columns.
  • Shell: Thin, curved, and shell-like.

Significance

• Each structure type represents the ingenuity of engineering.
• Provides deeper appreciation for structural diversity in everyday life.
