Scope of Services
Guido Morgenthal’s experience in the aerodynamic analysis of long-span bridges goes back to his PhD at Cambridge University, as part of which he developed the Computational Fluid Dynamics (CFD) solver VXflow.
The services of our firm in wind engineering today cover a wide range of numerical and experimental techniques:
- Analysis of Vortex-induced (VIV) and buffeting response of bridges, in final and erection condition
- Design of damping solutions to mitigate wind-induced response
- Investigation of guide vanes for mitgating VIV of bridges
- Prediction of aeroelastic instabilities such as flutter and galloping
- Analysis of the efficiency of wind shield on bridge decks, including design of shields; Prediction of increased load on bridge deck and effect on vehicle overturning effects
- Shape optimisation of bridge decks and high-rise buildings based on performance criteria for wind excitation
- Modelling of energy harvesting devices based on fluttering membranes (with Stanford University)
Shown below is a visualisation of a time-history buffeting simulation of Stonecutters Bridge during Erection.
