Shells & Systems 4 Lecture 28

Arches

• behavior
  • stabilization
  • resist thrust
• compression only

Shells & Systems 5 Lecture 28

Shell Types

• shape classifications
  • developable:
    • revolution (vault)
  • synclastic
    • doubly curved
    • same direction
  • anticlastic:
    • doubly curved
    • opposite curvature
  • free form

Vaulted Shells

• can resist tension
• shape adds “depth”
