Curved Bridge Design

  • Conference paper

Abstract

This paper presents a novel approach for the interactive design of linear structures in space. A method is introduced, that provides a maximum of formal freedom in the design of funicular, hence efficient, structures. For a given deck geometry, defined by a design driving NURBS curve via parametric modeling techniques, a tailored relaxation routine allows for controlled, real-time form-finding of the spatial funicular. Subsequently, the equilibrium of the deck is constructed using techniques from graphic statics, combined with a least-square optimization technique. Finally, the method is applied to a design example.

Keywords

  • Graphic Static
  • Bridge Deck
  • NURBS Curve
  • Tension Cable
  • Nodal Mass

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
