I am a structural engineer... I know short cut cal for building design but dont know any short cut calculation for bridges... Dose anyone know? Mahfuz...
I will have to tell you that as concerns the bridges I drive over, I don't want any "shortcuts" taken in their design and construction. Stephen Taylor Austin...
The shortest cut I know is f = m x a. If you understand that, you're half way there. Riadh ... __________________________________ Yahoo! Mail Mobile Take...
Of course you don’t use F=ma in bridge design. Newton’s second law is too broad to apply specifically in bridge design or any other design for that matter....
I still don't think the principle (F=ma) is very relevant to practical bridge engineering. This is true of Newton's mechanics generally (with the exception of...
Do any of you know what the "official" name is for that beautiful old concrete railroad bridge hat crosses the James River in Richmond, VA? I think it's used...
I know which bridge you're talking about having driven that stretch of the Powhite several times. I can't recall ever coming across a specific name. This page...
David, Thanks!!! That's the best help I've received yet. I even e-mailed and called CSX with my question, and they never bothered getting back to me....
... That was the old Atlantic Coast Line bridge. The Seaboard Air Line crossed the James south of downtown and went to Main Street station. I've been under...
It's possible that the bridge doesn't have a name. Not all bridges are given names. That seems to be especially true for railroad bridges. There are several...
Given the type of structure, it was likely built in the 1910-1930 timeframe, consistent with other similar large open-spandrel concrete rail bridges. -david ...
April 1948? Wow! Thanks for finding that. I'd love to see the picture, if you could scan it in and e-mail it. It sounds very interesting. But no name!!! ...
You're probably right. I used to think that every bridge must have a name, like "Brooklyn", or "Golden Gate". How could anyone spend so much time and money...
I agree with you 100%. Today's railroads are a lot different than the railroads of yesteryear. Back in the old days (1950s, for instance), the Boston & Maine...

... I know that this board is about bridges, but I can't let that last comment go. To characterize railroads as not caring about the public or their own ...
As a railfan, I can tell you that most railroads have a split personality regarding access by railfans ( and the public in general). The corporate flacks...

Yeah, it's a dead ringer for several of those concrete rail viaducts. The three Hallstead Cutoff viaducts come to mind immediately (Tunkhannock being the most...
