Salam everyone,
I doing some research on stiffened box girder bridges but I'm having some trouble finding the right one. If anyone has access to some papers or textbook examples or a bridge they designed it would really help me out.
Specifically I'm looking for a steel box girder bridge (trapezoidal or rectangular) that has its flanges and/or webs stiffened with welded longitudinal stiffeners. More than one stiffener is preferred (refer to attached image). I need the cross-sectional dimensions and stiffener dimensions too if possible. I have attached a few images as reference.
Thank you for your time and help in advance.
