Topological optimization of reticulated structures based on Genetic Algorithms

LI Yu-mei , LU Xiao-yang ( Research Institute of Modem Analysis and Design for Engineenng Structure, Shandong University of Architecture and Engmeenng, Jinan 250014,China)  
Genetic Algorithms (GA) is recently developed search strategy based on the rules of genetic evolution. It differs from existing mathematical programming methods in that the GA uses a population of initial points in contrast to the single-point approach by the traditional ones. The optimal solution by GA is no longer dependent on initial search values, and will guarantee a global optimum. Derivative calculation is not necessary and computer program is simple. Genetic algorithm is best suited for structural optimizations which have discrete variables. In this paper, the algorithm developed is used to deal with structure topological optimization problems with stress and displacement constraints. A numerical example shows that it is of high efficiency and good adaptability.
