An Evolutionary Approach for Layout Optimisation of Truss Structures
A new approach is presented in this paper for optimisation of framework structures where the number of joints and bars, as well as their locations, are allowed to change. Only the positions of loads and supports need to be provided, and the optimisation process is allowed to propose any suitable structural configuration based on a set of given quantifiable criteria. No underlying grid is used, thus neither topology nor geometry is restricted to a predefined array. The approach is based on, but is also distinct from, the principles of Genetic Algorithms. Two illustrative examples are presented to demonstrate the potential of the present approach.
