Download: Structural Analysis of Geodesic Domes.

Taken from Abstract: A project to house 40 families in the Maharashtra region of India which began in January 2005 was halted shortly after it commenced due to concerns over the loading applied to a series of geodesic domes which form a large portion of the whole complex. Vigyan Ashram, the organisation that manufactures the domes, issued a request for the development of an affordable computer program that would allow them to model the structural response of the domes. The ensuing research into the design of the geodesic domes and the development of a spreadsheet based finite element package are the subject of this dissertation.
