| Abstract: | A mixed optimal design algorithm is put forward,which applies mathematical planning law,full stress criterion method and genetic algorithm. This algorithm can be used to solve optimal design of prestressed steel structures,including two kinds of variables (continual variable and discrete variable) and three kinds of optimizations (shape optimization,section optimization and prestress optimization). Finally,arithmetic principle is analyzed and numerical example is calculated by the program,thus proving that the optimal design algorithm can be used. |
