Abstract: This study proposes an efficient biobjective cable force optimization strategy for concrete cable-stayed bridges aiming to maximize the safety of the structure under both the serviceability and ultimate limit state required ...

Abstract: In this paper, an improved particle swarm optimization (IPSO) method, which is based on standard particle swarm optimization (PSO) and a changing range genetic algorithm (GA), is proposed, and it is applied in the form-finding ...

Abstract: The buckling–anchorage system (BAS) is critical in the construction of cantilever casting concrete arch bridges. However, due to the limitations of the anchor positions, the BAS always needs a trade-off between material ...
