Study Notes
Bridge Redesign
- 55m long vehicular bridge, original width retained
- Original end abutments and piers
- 5.7m clearance over highway
- Out of use for 1 week in April and December
- Rural region, aesthetic design expected
- 4 supports on weak rock
- Soil/weak rock is consolidated and incompressible, no further settlement
- AS5100:2017 ULS and SLS considered
- Bridge deflection within Australian Standards
- Seismic and wind loading considered (laminar wind, turbulent wind considered in design for safety)
- Transient loads within bridge capacity
- Natural frequency different from vibration frequency to prevent resonance
- Inspiration from the Juscelino Kubitschek Bridge
- Concrete through arch bridge (suitable for 35m-200m spans).
- Arch will be adjacent to bridge deck, asymmetric
- Arch will use existing pier foundation
- Bridge will have minimal increase in weight
- Existing end foundation with bridge bearings
- Dampeners for earthquake loading and resonance
Bridge Construction
- Sufficient workers available throughout the construction period
- Site access for cranes, machinery
- Roads wide enough for 11m girders
- No impact on existing foundations and abutments
- Partial highway lane closure approved by council
- Detour set up, possible use of council or state roads
- Demolition and structure removal in initial 9-day period
- Highway beneath closed for demolition speed
- Arch construction and bolting in situ, cable connections, free hanging decks
- Simultaneous construction from both ends, decreases total construction time
- Prefabricated bridge deck segments
- Night-time construction for less disruption
- Parapet walls reinforced for safety
