[Abstract]:The basic principles of structural topology optimization are systematically expounded from three aspects: physical model, mathematical model and optimization algorithm. This paper introduces the method of bridge structure type finding by using topology optimization technology, and shows the evolution process of structure and the result of optimization in topology optimization. In view of the difficulties faced by the application of structural topology optimization technology in bridge search at present, the future research direction is discussed. The results show that the structural topology optimization method can obtain a reasonable and novel structure form in the conceptual design stage of the bridge, and has a good application prospect in the field of bridge type finding.
