Abstract
Tensegrity structures are pin-jointed truss structures compones of cables in tension and bars in compression. Due to their lightweight, complex shape topology and storage ability they can be a grate option for many application. This project deals with computation method and analysis of tensegrity structures. The aim is to determine how this structures are developed in practice. To do so, different form-finding methods are used to determine a geometry without the necessity of knowing the nodal coordinates, just the connectivities between elements. This allows the user to find new shapes for this type of strutures. As they are pre-stressed structures, it is important to determine their equilibrium position in absence of external forces. This process is called initial self-stress design. Once this initial state is known, it is possible to determine the structural behavior under external loads. For that reason, a non-linear Finite Element Analysis method for large displacements has been used to determine the response of the structure for a given structural load. This has been used then compare the pre-stressed structures to the normal pin-jointed structures by comparing the results of a linear method with the non-linea rone. Finally, a small review about the possible applications of tensegrity structures for space applications is given. Specifically, the case of a two-stage tensegritic mast has been studied to give an idea about how these structures can be used for this purpose.
