GEODESIC DOMES

• A geodesic dome is a sphere-like structure composed of a complex network of polygons.

• The triangle is a very stable shape; for example, a force applied to the corner of a rectangle can deform it into a parallelogram, but the same force will not deform a triangle.

INTRODUCTION

• Geodesic dome buildings highly resistant to forces as snow coverings, earthquakes, wind, and even tornadoes.

• The surface area of a geodesic dome is only 38% of the surface area of a box-shaped building enclosing the same floor space.

• There is less surface exposed to outdoor temperature fluctuations, making the building cheaper to heat and cool than a rectilinear structure

• A geometric dome supports itself without needing internal columns or interior load-bearing walls.

ADVANTAGES

• Movable structures may be built of polyvinyl chloride (PVC) pipe or galvanized steel conduit frames covered with plastic sheeting or parachute canopies.

• Large, permanent structures like arenas and factories have been built from materials like aluminum and steel frame struts covered with aluminum, copper, structural gypsum, acrylic, or Plexiglas panels.

CLIMATRON, USA

• By the mid-1980s, plastic panes were discolored and leaking.

• The Climatron was closed for a $6 million renovation in which all of the plastic panes were replaced with glass.

• Glass is more expensive than plastic, but it requires less maintenance over time. But because glass weighs an extra four pounds per square foot than plastic

• 2 feet inside the outer structure another dome was created to strengthen the structure.

• Climatron consists of 72 different triangular shapes.• There are 3625 glass panes

CASINGS

• Built in 2000 on reclaimed land in the Osaka Bay.• Seeming to float in the bay, accessed by a

submerged tunnel.• Covered by laminated glass.• Spider connections are used to hold the glass.• Steel struts were used to create dome.
