Dynamic and aeroelastic modeling of buildings and structures

Staff of WEFL have been involved in dynamic and aeroelastic modeling of tall and long-span flexible structures.  Aeroelastic effects have been investigated at WEFL through the use of section models and full aeroelastic models.  An example of an aeroelastic model designed and implemented at the WEFL is shown above.  It is a model of a long-span suspended roof over a railway station.  The effects of cavity beneath the roof turned out to be very significant.  A non-symmetric arrangement of trains (marked in blue) was found to be very detrimental to the aerodynamic performance of the roof.
