OK, thanks, but I will need some help getting from your book to "will a bridge made of W16x36 beams on 2' centers and 25' span support 90,000 pounds?"
I'm not an engineer. Again, thanks!
Does it really need to support 90k? What are the axle weights and spacings that will be on the 25 ft span at one time?
Also, you've been driving across those beams for years? Why not use the same size?
It sounds like the current design uses a center pier on one lane of the bridge, presumably reducing the span from 25 ft to 12 ft? I'm guessing that's the loaded lane.
I might give some thought to repairing the existing rusty webs if it's possible.
Just some things to consider.
