The Shape Analysis of the Truss Structures using the Genetic Algorithm |
| Abstract |
Genetic Algorithm(GA), which is based on the theory of natural evolution, has been evaluated highly for their robust performances. The optimization problems on truss structures under the prescribed displacement are solved by using GA. In this paper, the homologous deformation of structures was proposed as the prescribed displacement. The shape analysis of structures is a kind of inverse problems different from a general stress analysis and the governing equation becomes nonlinear, so GA was used for this problem. In this study, the shape analysis method in which not only the positions of the objective nodes but also the layout and sectional area of the member are encoded to strings in the GA as design parameters of the structures is proposed, and the accuracy and the effectiveness of the this method are examined. |
