CSM Optimization Tips for Bridge Design

In this tutorial, Jürgen Bellmann from SOFiSTiK provides a practical example of optimising a simplified pedestrian footbridge using the CSM (Construction Stage Manager) tool.

What You’ll Learn:

  • Effects of dead load on arches, hangers, and the superstructure
  • How to pre-stress hangers to minimise deformation and bending moments
  • Three powerful methods to optimise cable forces:
    1. Using fewer deformation targets
    2. Enforcing equal cable forces
    3. Implementing slip cables for symmetric load distribution
  • How to run a construction stage analysis based on optimised relaxed cable lengths
  • Tips and tricks like using len 0 and slip for a realistic simulation
  • A real-world pedestrian bridge case, including people simulation in mid-span

Whether you’re modelling a suspension bridge or a lightweight footbridge, this workflow can significantly improve your design precision and reduce manual trial-and-error.
