【Abstract】 This paper investigates the application of Genetic Algorithm(GA)in the optimum design of space grid structures. With GA’s characteristic of running side by side,the overall optimization and feasible operation,the optimum design model of space grid structures is established,and the optimum matching of the design variables is obtained.A numerical example for the three bar truss is given to demonstrate the reliability and feasibility of GA’s application.更多还原
