Abstract:
The configuration of long-span bridge is studied by the topology optimization method based on truss-like material model. By solving topology optimization of truss-like structures with minimal volume under stress constraints, the bridge configurations are established under different span-depth ratio, it’s found that the configurations are related to the span-depth ratio. The calculation results indicates that the optimal configurations are conducive to save the cost, improve the performance of structure and shorten the design cycle in typical long-span bridge structure.
