摘要

Tensegrity tower structures are innovative lightweight structures that feature a system of tension members arranged such that compressive members do not directly interact. In this article, a 7-stage tensegrity tower structure was designed and a modified genetic algorithm was used to optimize the prestress distribution within and shape of the tower. The optimization result shows the structure's lateral stiffness improves considerably compared with the initial model. Moreover, in order to determine the construction process, a construction scheme utilizing initial prestress and compensating prestress was proposed and a computational program named compensating prestress design program was developed. This program can help identify target tension and joint coordinates at each construction step such that the cable tension distribution in the completed structure meets designer-specified target values. Sensitivity analysis was also introduced in this program and Key Cable Theory was proposed as a result in order to improve the precision of compensating prestress design program. An illustrative example showed after applying compensating prestress design program, tension errors were all controlled within a small range.
