In the USA the use of curved girder
bridges has steadily increased year by year and is now estimated
to represent 25 percent or more of the entire steel bridge market.
With curved girder structures significant torsional stresses must
be accounted for at the design stage and careful consideration is
also required to ensure their safe erection. To arrive at
meaningful results for curved girder bridges grillage-based
analyses are not sufficient. Full 3D modeling and analysis is
required to accurately model the beams and, in particular, to
derive the tension and compression forces in the K or X
frame bracing members.
LUSAS Bridge is ideal for curved
girder analysis and has many useful modelling and results
processing features to help you optimise your design.
