A panelized complex polyhedron structure can be constructed quickly and inexpensively from a plurality panels. According to one embodiment, the structure includes a plurality of panels, wherein a first panel comprises an integrated connecting feature formed unitarily with the first panel and including a faceted feature connected to a plain end of a second panel. According to another embodiment, the first panel includes integrated connecting features including a plurality of planar faceted features, wherein one of the faceted features is connected to a plain end of the second panel. The plurality of planar faceted features are oriented at angles selected to enable a plurality of panel connections necessary to construct the structure. In one embodiment, the panel comprising the integrated connecting features is formed unitarily.

A joint system for joining polyhedric facet elements together. Polyhedrons have a plurality of facets. The polyhedric facet elements have facet planes that are generally congruent with the facets of the polyhedrons in which they are found. Various facet elements occupy angular relationships such that they can be joined in rigid stable joints by means of key elements where the planes of the key elements extend generally perpendicular to the planes of each of the facet elements. The joint system is suitable for inter-polyhedron joint systems where the joints include four joint elements, three of which are in the respective polyhedrons that are to be joined, and the fourth is a key element perpendicularly disposed between the other three joint elements. The joint system is likewise suitable for intra-polyhedron joint systems where there are three joint elements, two of which are in the polyhedron (in-polyhedron) and the other is a key element that extends in perpendicular relationship inter-facet between the two in-polyhedron facet elements. The intra-polyhedron embodiment of the joint system is particularly well suited to permitting polyhedron structures to be formed with alternating open and closed facets for aesthetic, structural, and other utilitarian purposes.

A strong, lightweight structural system wherein curved structural elements are tangentially joined. Compressive forces are distributed in a near continuous manner throughout the matrix, and tensile forces are present primarily to brace, support and pre-stress the compression net. The system is scalable from molecular through architectural levels, and finds many applications in dome shaped and spherical structures. The structural system also provides a force interaction model that is applicable to a broad array of real and theoretical problems.

The present invention relates to a building system comprising prefabricated plates for self-supporting space boundaries. To enable simple construction of load-bearing structures that are versatile in three dimensions and that enclose spaces, plates, at least some of which are disposed at different inclinations, in the form of flat, slanted prisms are joined by their side faces directly to one another and/or via bars in the form of long, slanted, square prisms; adjacent connecting faces are congruent, and the square faces of different bars, are disposed parallel or perpendicular to one another.

A tensegrity structure is formed from a plurality of interconnected tensegrity modules. Each module includes several column-like compression members and tension elements run between ends of the compression members to define a polyhedron. The tension elements form the edges of the polyhedron and intersect at the vertices of the polyhedron. The interconnected modules are joined to each other with triangular faces abutting but with the edges and faces of the abutting triangular surfaces of the respective modules rotated 180.degree. away from superposition and with the vertices joined to tension element edges, being joined at a point located one-half or one-third of the way along the length of such edge.
