Abstract
The main interest of the paper is at the design and development of deployable dome structure. In a deployable system the constituting elements moves through different spatial positions. A deployable system needs the adequately designed mechanical connections to accommodate the required movements of the elements. In addition, the selection of the appropriate grid formation for the given number of the constituting members affects the resultant quality of the deployable system. For instance, it is always desirable to use the minimum number of components for the economy and practicality; however using too few may result in the greater discontinuity in the curved form, and the greater internal stresses for the elements. The paper presents an on-going research in the development of a deployable single meridian dome structure in application of straight members with the mechanical system to minimise the internal stress during the folding/unfolding process.
