Hybrid steel girders
Hybrid steel girders
(OP)
AASHTO Guide Specifications for Horizontally Curved Steel Girder Highway Bridges do not provide any information on hybrid girders. Do I have to assume that we can't use hybrid girders on curved alignment due to lack of Sprcification?





RE: Hybrid steel girders
They go on to state that the 1993 Guide Spec does provide for hybrid I-girders but not box girders.
If you happen to be using the AASHTO LRFD code, Article C6.10.1.3 states that "... these provisions can be safely applied to all type of hybrid sections..." These provisions address curved girders.
I take all this to mean that if you're using the AASHTO LRFD Specs, you're all set. I also think that it's acceptable to use the 2003 Guide Specs in conjunction with ASD or LFD in the AASHTO Standard Specs.
