  1. Schlaich’s Use of Cable-stays By Avery Choi & Shaun Lee

  2. JORG SCHLAICH • Born in 1934, Stuttgart, Germany • Studied Architecture and Structural Engineering • Worked for Leonhardt • Setup own firm: Schlaich Bergermann and Partners

  3. Definition of Cable-Stayed Structures • A cable-stayed structure is one that employs cables to transfer its loads to the supports. • Cable-stayed structures must have: • Pylons • Diagonal cable-stays

  4. Cable-Stay Configurations Radial Configuration VS Parallel Configuration

  5. Why use Cable-Stays? • Versatile • Low construction costs • Light and elegant Why not? • Susceptible to wind forces • Complex computer analysis required

  6. Schmehausen Cable-net Cooling Tower • Social: Architects and Engineers loved it • Symbol: Landmark structural engineering in Denmark • Scientific: Combined the use of cable-stays with cable nets

  7. Pedestrian Bridge in HornKiel, Germany

  8. 2nd Hooghly River bridge • Location = Calcutta, India • Deck width = 35m or 6 Vehicle lanes • Spans total of 821m = 182 – 457 – 182m • Towers = 135m high • Material = steel with concrete cladding

  9. “If I am proud of anything and happy above that, then it is this bridge!” By Jorg Schlaich

  10. Santiago Calatrava

  11. Conclusion • Cable-Stays can be used for a variety of purposes and design constraints • Schlaich’s cable-stayed structures are: • Efficient – Hooghly river bridge • Economical – Cooling plant • Elegant – Folding bridge
