In this paper the key problems related to the structural theory of the sheet space system are discussed. The principles for selection of the structure form and the mechanical analysis are described briefly. For the purpose of simplifying the design of this system the main functions of the professional software is narrated at the end and some related diagrams showing the influence of imperfection of structure on stability are also attached to the paper.

In this paper, the structural principles and the engineering practice about the sheet space structure are summarized. The key problems in structural analysis of the system - strength of the laminated composite plates and stability of the structure are described. The reliability of the analysis is verified by model tests of the structure.
