Hans Wilsdorf Bridge in Geneva, Switzerland
Engineering Office: amsler bombeli et associés sa
Software: Scia Engineer

Upon completion in 2012, the Hans-Wilsdorf Bridge will have a span of 85.4 meters and a roadway that is 15.5 m wide. 40x40 cm thick steel sections give the structure its elliptical shape. Given the complexity of the geometry of the bridge, the structural designers developed several models with very sophisticated calculations. Thicknesses and steel grades were optimized through the input of 250 parametric cross-sections.
