Abstract:

First, the physical model, the mathematic model and the algorithm of structural topology optimization was stated. Next, the application of topology optimization in form finding of bridges is elaborated via some examples, and the evolution process and the final layout of structural topology optimization were presented. Finally, some issues of future research were suggested to improve the application of topology optimization in form finding of bridges. The result shows that structural topology optimization can derive a reasonable and heuristic layout in the conceptual design phase, and has a promising prospect in form finding of bridges.

Key words:bridge engineering; topology optimization; density method; form finding of structures
