Abstract
To provide a structure model search method, a structure model search system, and a structure model search program capable of searching for a more appropriate structure model.SOLUTION: The structure model search method includes a search step of using a genetic algorithm, generating a plurality of structure models corresponding to the structure, and searching for a structure model of which fitness is superior to other structure models from among the plurality of generated structure models, wherein the structure model includes information indicating a shape and a position of each of a plurality of members constituting the corresponding structure, the fitness is calculated based on a first target variable of the corresponding structure model and a design constraint penalty of the corresponding structure model, and the design constraint penalty includes a model-by-model penalty obtained for each of the plurality of structure models generated in the search step.SELECTED DRAWING: Figure 8
