You will find information on such steel bridege items in

Is your structure suitably braced? SSRC 1993

The WSDOT (Oregon) Bridge Manual is online in pdf format and may have information on that as well (haven't checked).

OF course, for known joint boundary conditions a 3D FEM analysis will be revealing.
