摘要：
Directed at the feature of structural design variable of prestressed space latticework, the paper puts forward a optimum design method based on discrete variable and genetic algorithm. The method puts cross section of member bar and prestress in a same level variable space, it's individual codes externalize genetic gene of two variables at the meantime, keep out of error effect created by rending design space and cascade optimum. The optimum method adopts improved means of sufficiency transformation, best retention, self adapting inheritance and so on, to improve the defects of premature phenomenon and bad ability in finding the best.
