Schlaich’s Use of Cable-stays 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: ØPylons ØDiagonal 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

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

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

Santiago Calatrava

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