STRUCTURAL ELEMENT, TETRAHEDRAL TRUSS CONSTRUCTED THEREFROM AND METHOD OF CONSTRUCTION ABSTRACT A three-dimensional, tetrahedral truss and its method of construction are provided. The truss com- prises a three-dimensionally periodic skeletal array of an interconnected plurality of skeletal-tetrahedric units, the array being in the pattern of the cubic-dia- mond crystallographic structure (FIG.7). In one embod- iment, each of the skeletal-tetrahedric units is an articulated arrangement of struts joined in the pattern of an equilateral skeletal-tetrahedron (FIG.4). In another, more preferred embodiment, each of the skele- tal-tetrahedric units is a skeletal arrangement of elongate members joined in the pattern formed by the face members of a cubic-diamond unit-cell (FIG.10), and is preferably assembled from four hexagonic triplanar- rings (FIG.10A) being of the form created by joining six bilateral-elements in a closed ring, triplanar pattern (FIG.9), the bilateral-elements each having equal sides and having an included angle of about 109°28' (FIG.8).
