See I learn something new every day. I know geometry but not much about structural engineering, so I saw an arch and figured it was an arch bridge. But now I have been inlightened, cool. jt (...) (24 years ago, 8-Dec-00, to lugnet.trains)

I'm not a civil, thanks for refining my critique. (...) Oh, indeed, it looks nifty. It's just not an arch. I'm not competent to comment on whether trusses can't be pinned, though. While we are identifying arches, though, I thought Ben "April Fool" (...) (24 years ago, 8-Dec-00, to lugnet.trains)

(...) I was going to leave this, but now that you started... I agree that is not a arch, and I expect that is was modelled on a truss. However, I'd call it a frame as it is pin jointed (trusses, I think are not). However, to be a frame all the (...) (24 years ago, 8-Dec-00, to lugnet.trains)

(...) Well, no, I'd have to categorise it as a type of through truss. Hell Gate and Sydney Harbor Bridge, for example, are suspension arch bridges. Essentially all members below the arch are in tension and the deck is suspended from the arch. (The (...) (24 years ago, 8-Dec-00, to lugnet.trains)

Looks like the arch is made from 4.5v curved rails, right Arne? I really like the look of it, very sturdy and even looking. Nice job. I'd have to argue with the "two" arch bridges though, I have a technic arch bridge that I made earlier this year. (...) (24 years ago, 8-Dec-00, to lugnet.trains)

(...) Love that bridge. It looks like the span carries the whole load. What I mean is that a lot of people use bricks under the track to stiffen the track, but your track is supported at six or maybe 8 points, and the rails and tiles do all the (...) (24 years ago, 8-Dec-00, to lugnet.trains)
