Structural Topology Optimization of Configuration in Long-Span Bridge Based on Truss-Like Material Model
摘要
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 config-urations are conducive to save the cost,improve the performance of structure and shorten the design cycle in typical long?span bridge structure.关键词
