Abstract
For large or complex structures, due to the large amount of design variables, structural optimization often takes too much time. This paper studies how to define the appropriate component size in a specific structural component, so as to achieve the optimal distribution of structural materials and achieve the most economic design of the structure on the premise of meeting the safety indicators of the structure. Based on the traditional Bidirectional Evolutionary Structural Optimization(BESO) algorithm, multi-stage objective algorithm is developed to accelerate the structural optimization process. Taking a 10 story steel frame shear wall plane model as an example, the optimization aim stage is defined by the constraint redundancy values. And the rationality of the method is proved by the optimization results.
