Free download of : Structural Analysis of Geodesic Domes
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. The domes had soil packed over them, a condition which was never anticipated in the original design.
The need for a method to model the structural response of the geodesic or “Pabal” dome was highlighted by Vigyan Ashram, the Non Governmental Organisation (NGO) that manufactures the domes; this dissertation describes the research into the Pabal dome and the development of a bespoke finite element analysis (FEA) package capable of running in Microsoft Excel.
Vigyan Ashram locally produces the geodesic domes as do-it-yourself kits for the lower middle class of both rural and urban populations. The original design was adopted in the aftermath of the 1993 Killari earthquake, aiming to provide durable, low cost housing capable of withstanding the earthquakes, rains and winds of India for those that lost their homes …..
