Modified Type VI Girder
Modified Type VI Girder
(OP)
I have to design a single span 47 meters bridge.
I've learned that we can modify the section of standard AASHTO girders, particularly the Type VI since the maximum span for this is about 43 meters.
Do you have any pointers in the design? Any additional checking for the design, aside from the usual girder design?
Based on your experience, what will be the new section of the girder? height? Thanks!

RE: Modified Type VI Girder
Aside from that, if I was redesigning an AASHTO standard girder, I would start by either recreating or finding the calculations for that design and making sure I met the minimum requirements it had. If it deflected L/1000, I would make sure I matched that. If it had a FS of 4, so would I.
And as a side note, once you change their design, you own it.

Yes sir, It means to changes dimensions (mainly the height) to modify it, aside from increasing the number of strands
