One area in which space grids are set to advance in the future is the field of deployable and foldable structures. The property of deploy ability in a space grid structure may be used just once or many times. These space grids can be assembled in compact form, transported into outer space and then deployed in a ‘one-off’ operation. Alternatively, temporary transportable buildings can benefit from the use of rapidly deployable structures. There is need to conduct analysis of newly introduced deployable space structure for large spans so that they could be used in stadiums or large open spaces or grounds where the entertainment is hindered sometimes due to unfavorable weather conditions. A deployable scissor grid can be considered as a kinematic linkage of scissor units, also known as pantographs or scissor-like elements. Scissor grids are created by interconnecting multiple scissor units at their end points. Translational units allow constructing spatial double-layer scissor grids with a myriad of shapes and a foldable deployment behavior, of which the design can be simplified to a set of two-dimensional problems, as all its upper and lower layer nodes are located on parallel line. Analysis and design issues of a new concept of deployable structures featuring stable and stress-free states in both deployed and collapsed configurations and behavior of these structures during their deployment[1] procedure, which is associated with geometric compatibility requirements have to be studied thoroughly.
