| Abstract: | The optimization mathematical model for discrete cross-sections is established with the constraints of strength, rigidity, stability, minimum cross-section and the structural deflection of double-layer space grids members and solutions are obtained by using the genetic algorithm. A example indicates that the genetic algorithm can be applied in the optimal design of double-layer space grids and reliable results can be obtained. |
| Keywords: | double-layer space grids optimal design discrete cross-section genetic algorithm |
