By Avery Choi & Shaun Lee
JORG SCHLAICH
• Born in 1934, Stuttgart, Germany
• Studied Architecture and Structural Engineering
• Worked for Leonhardt • Setup own firm:
Schlaich Bergermann and Partners
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:PylonsDiagonal cable-stays
Cable-Stay Configurations
Radial Configuration VS Parallel Configuration
Why use Cable-Stays?• Versatile
• Low construction costs
• Light and elegant
Why not?• Susceptible to wind forces
• Complex computer analysis required
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
Pedestrian Bridge in Horn
Kiel, Germany
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
“If I am proud of anything and happy above that, then it is this
bridge!”By Jorg Schlaich

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