Abstract: A composite building component including a center web and opposed elongate flange elements united to opposed edge margins of the web. The edge margins of the web seat within web-receiving channels defined in the flange elements, and are compressed through the act of inserting the margins into the channels during the assembly of the component. An adhesive bonds the edge margins in place within the channels. A method of making a composite building component comprising a web and flange elements united to opposed edge margins of the web.

Abstract: A plurality of mathematically interrelated modular structures are disclosed which are based on a series of minimal surfaces bounded by skewed polygons. Some six basic modules are described which are capable of being interconnected in various combinations to form finite volume enclosing structures. Appropriately scaled, the modules could be used as structure toys, to create playground equipment or, for the construction of habitible structures. Utilizing these structural modules, it is possible to construct large assemblies having parallel planar structures within the enclosed space which could be considered floors and ceilings of multilevel structures.
