Abstract EN
To obtain the optimal uniform prestress of a tensegrity structure with geometric configuration given, a novel method is developed for prestress design of tensegrity structures by utilizing the artificial fish swarm algorithm (AFSA).
In the beginning, the form-finding process is implemented by solving a linear homogeneous system concerning the self-equilibrium system.
The issue is subsequently performed as a minimum problem by regulating the value of an objective function where the unilateral condition and the stress uniformity condition are entirely considered.
The AFSA is adopted to search for the global minimum, leading to a set of initial prestresses that guarantee all the above conditions.
Two illustrative examples have been fully studied to prove the accuracy and efficiency of the presented approach in prestress design of tensegrities according to the practical requirements.
Furthermore, the numerical examples investigated in this paper confirm that the AFSA has explicit advantages of rapid convergence and overcoming the local minima.
