Biosphere Montreal • Geodesic Dome

Last crawled date: 1 year, 1 month ago

Final geodesic configuration • The Biosphère, as built, after truncating to a 3/4 dome • Geometry, from the 'equator' down, is modified to provide struts parallel to the ground • This modification, or debasement, of the true geodesic configuration, allowed the 3/4 dome to 'sit flat' on the foundation • The Biosphere was originally built for the 1967 World Exposition, as the United States pavilion, designed by Richard Buckminster Fuller and architect, Shoji Sadao • The Biosphere dome is 250-feet in diameter and 200-feet tall • The outer shell (blue) is a 16-frequency, class I tessellation of the icosahedron • The inner shell (red) is a 32-frequency, class II icosahedron tessellation • The struts in-between (yellow) connect the inner and outer shells, producing a unified tetrahedral-truss structure #biosphere #biosphère #Buckminster_Fuller #expo #Geodesic #icosahedron #montreal #pavilion #Shoji_Sadao #tetrahedral_truss
