Abstract
The structures with pentagonal contour can be used as independent roof or a part of UNIDOM type domes. In the paper are discussed some possible proposals for such structures with different bar patterns. It is continuation of author's previous works presented partially on international conferences: IASS, SEWC, SEMC and LSCE. The system of UNIDOM space bar structures was investigated firstly on models, using children plaything, and next by Zometool kit. There is possible to construct even complicated domes, composed from two kinds of bars and one node, only. The elementary substructures can be designed as: plane single- or double-layer (triangular, rectangular and pentagonal, the last can be convex or concave) with possible theirs any combinations. It permits to obtain many architectural effects. The UNIDOM type dome has principal nodes located in vertexes of rhombiicosidodecahedron, with coordinates not positioned in regular net of points, but substructures are regular.
