Banyo Station Composite Pedestrian Bridge revisited
Back in 2016 Queensland rail commissioned the design of a composite pedestrian bridge. The site of the bridge had the one of the highest rates of illegal rail crossing in the network. In designing and engineering such a structure there are many challenges and considerations to be overcome.
- The installation was over 25,000v live power lines.
- Around 600 daily passengers use the station, therefore the installation should cause the least amount of inconvenience.
- Maximum design life with minimal life cycle cost.
- Offsite construction.
- Minimal maintenance.
The resulting design was over 9m tall and 16m end to end. Manufactured and constructed from non-conductive FRP profiles and grating. The main horizontal element at 2.9m high with 3m of internal clearance.
FEA modelling was carried out to ensure that the design met all the load requirements. The final structure performed as per the modelling results. The total structure weighed in at 6 Tonnes. A similar structure in structure in steel would be around 21 Tonnes.
Part of the considerations of the bridge was to deliver low ongoing maintenance program. If required parts of the bridge can simply be unbolted and replaced. No hot works or special permits required.
The structure was designed to meet the flame spread burning characteristics of ASTM E84 and the self-extinguishing requirements of ASTM D-635.
Composite Engineering offers complete design, fabrication and installation services.
We can manage your project from concept to final delivery. Our FEA modelling and testing means we can engineer the project to meet the highest of requirements.
All of our structures are fabricated in house to our exacting standards. Our attention to detail and years of experience mean that your project, no matter how large or small, will be delivered on time and on budget.
