Structural topology optimization of steel girders in cable-supported bridges

Girder design for suspension bridges has remained largely unchanged for the past 60 years. However, for future super-long bridges, aiming at record-breaking spans beyond 3 km, the girder weight is a limiting factor. From the application of topology optimization, a method to identify material-efficient structures, a new girder design concept is proposed, demonstrating possible weight savings in excess of 28 percent while maintaining manufacturability.
