Bancel Viaduct example in BEDAS
Example of Bancel Bridge (France), dynamics analysis under moving French fast speed
train(TGV) computed by BEDAS software:
The Bancel viaduct situated in the South-East of France, is a fast speed train(TGV) railway
bridge . The viaduct is continuous bridge of 5 spans and 3sections kinds. Section 3 is a
cracked concrete region, and the modular ratio between steel and concrete elastic
modulus taken in this example is10 under live loads. The coefficient of damping is take
equal 0.5% of the critical damping and the train speed is varied from 150 to 400 km/h. and
the viaduct is simply supported.
ShapeDesigner Software computes geometric properties of the transverse section (c) and are
