Von Mises - A paradigm shift in bridge design

VON MISES develops parametric footbridge projects based on the geometry of the landscape, the continuous search for simplicity, and the use of unique shapes that emanate from structural behavior. The designs are based on bridges previously built by ANTA.

The development of the Von Mises, Monocontentio, and Bicontentio prototypes consists of applying a particular design philosophy used by Mario Guisasola in multiple pedestrian bridges that can now be systematically implemented by other professionals.

The systematization of the footbridge design aims to save time and engineering costs without necessarily having to rely on simplistic solutions.

Parametrization is linked to systematization, and it allows us to quickly and accurately particularize a design for a specific case.

Structural efficiency is obtained by using shapes that emerge from the beam’s structural behavior and implementing the graphs that interpret such behavior as structural silhouettes.

The topography of the site determines the bridge and defines its structure. A vertical wall translates into a simple support and a slope into a fixed end. The embedding is achieved by means of an ancillary span that merges with the slope. Once the structure is defined, its bending stress diagram determines its silhouette.

The typology implemented for all prototypes corresponds to a twin-girder steel bridge composed of two main box girders.

The main girders may be simply supported, fixed at one of the abutments, or at both ends.

The Von Mises, Monocontentio, and Bicontentio prototypes have undergone an in-depth structural analysis that has verified their structural efficiency and good dynamic behavior, achieving the maximum degree of comfort.
