Geodesic dome of polystyrene and concrete

Structurally, the geodesic dome is a space truss and is the strongest known straight-line form enclosing space. It is efficient as well as strong; there is no straight-line geometric form that requires less surface skin to enclose a given amount of space than a geodesic dome. In the concrete and polystyrene dome described, folds in the concrete shell replace the straight bars. The folds, however, act just as the bars would to transmit loads to the foundation. The article discusses the foundation requirements, cutting and assembling the triangular panels; setting steel and applying concrete; interior and exterior finishes; and the costs and material quantities.
