DYNA Grip® Stay Cable System
DSI’s cable hardening system has been developed to protect the stay cables effectively against multiple threat scenarios for all stay cable sizes.
- Any kind of mitigation level in terms of specific customized threat scenarios and the required strength of the protection system can be taken into consideration.
- Highly effective protection material can be easily adjusted to requirements and threats
- Numerical simulation and physical testing is carried out using expertise from Fraunhofer Institute for High Speed Dynamics (Ernst-Mach- Institute)
- Validation of different scenarios with specific threats following bridge security guidelines (e.g. AASHTO)
- Therefore, DSI’s Cable Hardening system is designed according but not limited to the typical and notable threats as shown in table below
- Adaptable for bridge retrofitting applications using half-shell technology
Cable Hardening shows advantageous performance characteristics:
- Eases installation and is adjustable to different bridge construction methods
- Can be adjusted to any kind of bridge construction layout within anchorage and transition zones
- Incorporates adjacent functional cable units like dampers either internally or externally
- Allows easy inspection and maintenance of the protection system itself but also the stay cable system in general
