Steel bridge, not composite bridge.
For steel design SOFiSTiK can perform stress checks and c/t checks for beam sections. Buckling and lateral torsional buckling check for members (based on design elements). And also stress checks for QUAD elements.
Please see our online tutorials
and also our online verification manual examples
Thank you for the links, they are good documents for steel building design learning.
AFAIK, eurocode has different codes for steel building and steel bridge design.
Is it possible for Sofistik to publish a comprehensive steel bridge example in the (near) future?
