Static Alternate Path Analyses on Tensegrity Systems Considering Effects of Self-Stress Distributions

Tensegrity systems are innovative systems in the spatial structures field and refer to a special type of tensile structures that can offer an alternative to traditional space structures. These systems are defined as any given set of cables connected to a set of struts in which cables connectivity must be able to stabilize the configuration (Skeltton and Oliviera, 2009). The self- stresses contribute to the system’s rigidity and stability. In tensegrity systems, a number of members are critical, with the loss of any of them likely to produce serious strength reductions. In practice, members of a tensegrity system may be lost due to a poor member node connections or geometric imperfections, e.g. lack of fit. In fact, having one or more faulty connections in a structure, containing hundreds of connections, is a realistic possibility. In such a case, it can be argued that this member has in effect been lost.
