The design of wind susceptible bridges requires an in-depth
understanding of all aerodynamic aspects, which must be addressed
during the design and construction phases of a project. Our
specialists have a vast range of skills in this area and our bridge
designs have operated in both temperate, monsoon and typhoon
climatic conditions. In particular, we originated the vented box
girder approach which has been used successfully in the typhoon
environment of Hong Kong, where gust speeds are in excess of
330km/h.
Taut strip model testingWe have experience in
the following types of wind tunnel testing:
- Terrain
- Sectional
- Taut strip
- Aeroelastic
- Cable stay
CFD simulation for Stonecutters bridgeIn wind
tunnel testing we understand the technical specifications required
for the construction of models plus the applied wind effects. This
includes an assessment of the model scale and the determination of
the frequency regime.
We have enhanced our aerodynamic capability by developing in-house
computational fluid dynamics (CFD) software, enabling us to
investigate the preliminary performance of deck sections in fluid
flow prior to testing in the wind tunnel.
Some projects where the design required wind tunnel testing to be
undertaken included:
Suspension Bridges
- Tsing Ma Bridge, Hong Kong
- Tsing Lung Bridge, Hong Kong
sectional model testingCable Stay Bridges
Footbridges
- Boundstone Lane Footbridge, UK
