Elegant Cable-Stayed Bridge Design over Upper Hanover Street

This detailed design project aims to create a safe passage for pedestrians and cyclists over Upper Hanover Street in Sheffield, improving safety, traffic flow, and connectivity with major university developments. The cable-stayed bridge design integrates into the area, providing multiple access points for pedestrians and cyclists. The ramp design includes typical spans and flexible connections, while the tower design features concrete-filled circular sections. Construction will involve phased processes and prefabricated deck sections. The sustainable design focuses on durability, low maintenance, and economic viability, encouraging local economy improvement. The project concludes with the creation of a landmark structure that is socially inclusive and beneficial for the community.

  2. Aims and Objectives • To provide a safe passage for pedestrians and cyclists over Upper Hanover Street • To reduce the use of road level pedestrian crossings, thus improving safety in the area and traffic flow at Brook Hill roundabout • To devise an elegant and sustainable design that will act as a landmark for the University of Sheffield • To provide a direct route between the major university developments

  3. Location

  4. Location • Direct links to major university developments • Does not impede on existing buildings • Requires no permanent road closures • Integrates an existing cycle route • Requires a long span bridge solution

  5. Cable-stayed Bridge

  6. Cable-stayed Bridge • Landmark structure • Integrates into surrounding area • Provides vital links using multiple access points • Incorporates pedestrian footpaths, cycle lanes and disabled access points

  7. Ramp Design • EC3 design • Deck • Simply supported • Typical span 8m • Flexible end plate connections using M20 ‘hollo-bolts’ • Columns • 203x203UC60 sections • Simple connections • Lateral stability provided by diagonal bracing

  8. Ramp Design RAMP ELEVATION

  9. Bridge Deck • Static Analysis Loading: - Permanent: Self weight (including deck plate) - Imposed: 5kN/m2 - Wind: Max 0.8kN/m2 (acting transversely or in uplift)

  10. Bridge Deck • Dynamic Analysis • Simplified model • No mode near pedestrian mode frequencies

  11. Bridge Deck • Thermal Analysis • Bridge deck requires a movement joint • Roller joint will be positioned at one support

  12. Towers • Tower • Designed as 15m cantilever (concrete-filled circular hollow section) • Maximum bending moment 9000kNm at base • Column tapers from 1500mm to 500mm, 25mm wall thickness • No incline due to space issues

  13. Cables and Base • Cables • Maximum cable tension 366kN • Tieback tension 2736kN • 50mm diameter • High tensile strength steel • Bases • Treated as 6m tall, reinforced concrete shell, around base of . tower • Slab: 145 deep, T10 @ 250 centres (T8 @ 300 secondary) • Beams: 500x200, 4T10 bars with T8 links @ 300 centres • Columns: 800x200, 4T10 bars with T8 links @ 300 centres • Assumed to act as an encastre joint for the tower

  14. Construction • Phased construction • Construct reinforced concrete bases • Transport individual prefabricated deck sections to site • Install ramp columns, bracing and deck (giving safe access to tower bases) • Erect support towers • Connect deck sections in series and anchor support cables in tower • Large cranes will be required • Difficult to maintain two lanes of traffic • Temporary stability needs to be provided to bridge deck during construction

  15. Sustainability • Environmental • Durable and low-maintenance design • Limited range of material options • Locally source steel and concrete aggregate • Reduce transport and waste during construction • Provides link to existing cycle path • Social • Provides direct links to major university developments • Incorporates pedestrian footpaths, cycle lanes and disabled access points • Economic • High initial cost may be mitigated using advertising • Low running costs • Encourages improvement in local economy

  16. Conclusion • Landmark Structure • Provides direct links • Socially inclusive
