Regardless of any scale, space structures are widely applied for the field of engineering by using the enhanced mechanical properties, e.g., high stiffness and strength-to-weight ratio. Flexibly jointed structure as a type of space structure is constructed of flexible joints and beam members. Li this study, we proposed a newly structure with flexible multi-linkages and re-entrant spaces, and we evaluate its elastic characteristics as Poissoris ratio, which is a mechanical criterion for solid deformation. The numerical results show that the propose structure exhibits negative Poisson's ratio for high joint flexibility, and it also produce an expansion deformation subjected to local rotational moments.
