Text of The Geodesic Dome Geo (earth) Desic (divided). Geodesic Domes are energy and material efficient

  • Slide 1
  • The Geodesic Dome Geo (earth) Desic (divided)
  • Slide 2
  • Geodesic Domes are energy and material efficient
  • Slide 3
  • Geodesic Domes can span large interior areas Notice that there are NO interior support columns
  • Slide 4
  • Discovered by Buckminster Fuller Bucky Fuller in front of Casa Manana Theater in Fort Worth Texas
  • Slide 5
  • The The geodesic dome ratio took two years to calculate without a computer. Complicated Math?
  • Slide 6
  • Simple Directions! Find an existing Geodesic ratio and create triangles.
  • Slide 7
  • Use any material Warning! Food will melt!
  • Slide 8
  • Which ratio do I use? Radius = 30 cm To build a 2V Dome with a radius of 30cm 35 Struts 18.54 cm each 30 Struts 16.4 cm each To build a 3V 5/8 Dome with a radius of 30 cm 30 Struts 10.46 cm each 55 Struts 12.11 cm each 80 Struts 12.37 cm each To build a 4V Dome with a radius of 30 cm requires: 30 Struts 7.6 cm each 30 Struts 8.86 cm each 60 Struts 8.84 cm each 70 Struts 9.39 cm each 30 Struts 9.75 cm each 30 Struts 8.96 cm each

  • Kit homes are not a new Idea
  • Slide 10
  • Square houses have natural fatal flaws
  • Slide 11
  • Domes can range from very small
  • Slide 12
  • To very big
  • Slide 13
  • The dome at Epcot has been through MANY storms.
  • Slide 14
  • More triangles mean more strength and stability These two designs are filed with the United States Patent office.
  • Slide 15
  • Geodesics are more common than you might think. South pole research station Pop-up tent Dopplar weather radar Football (yes, this is called a football)
  • Slide 16
  • Your Turn! Research, design and build a Geodesic Dome. You may use any dimensions and any type of material for construction. You must turn in the dome and a data sheet showing which dome ratio you used along with all math steps. Also show the predicted and the actual dimensions of your dome.
