Predicting damages in Cable Stayed Bridges

Stay Cables of the Fred Hartman Bridge
The Northeastern University in Boston uses the middleware technology by Techila to speed up the study of vibration of “cable networks” used bridges.

The research project gains benefits of the Techila solution especially on large samples. Techila also enables scaling of the computational time proportionally with the size of the computing infrastructure.

Cable networks are structures, which consist of inclined stays in Cable Stayed Bridges. These are employed to reduce susceptibility of the inclined stays to wind hazards on long-span bridges. The structures may get damaged over time, risking the safety of the bridge.

Cross-ties are widely used for mitigation purposes. The research team at the Northeastern University develops a framework for the analysis and prediction of oscillations on cable networks in the presence of stochastic disturbances. The motivation for this research comes from damages, which have been reported to the cross-ties on Fred Hartman Bridge. The goal of this research and development is to enable prediction of similar damages.
