| Abstract |
In this study, micro genetic algorithm is used to find an optimum weight of muti-stage tensegrity grid structures. Tensegrity structures which consist of discontinuous compressive members(Struts) and continuous tensile members(Cables) belong to a general pin-jointed system. Optimum design of tensegrity structure obtained optimum sizes of cross-section and prestressing force parameters, satisfying a set of specified constraints. The present approach is verified by 72-bar truss example showing good agreements with previous results. The minimum weight design of tensegrity structures are performed for various magnitudes of pretension and optimal prestressing forces are also found for various configurations of tensegrity structures. |
