ABSTRACT. The main point of structure optimization, although being economical, is that none of the engineering conditions and criteria must be neglected. Various methods such as Genetic Algorithm, Particle Swarm Algorithm, Annealing Algorithm and so on, have been used for optimizing the structures up to now. In this research, a new method called ‘The Imperialist Competitive Method (ICA)’, which is inspired by a social-human phenomenon, is used in topology, dimension and weight optimization of a structure and it is shown that is even useful for constraint problems as well. Conclusions show that the resulting diameters for structure partial sections are better than other optimization methods.

Keywords: optimization, truss, imperialist competition, applying constraints, topology optimization, weight optimization
