In yesterday's blog I wondered if a steel girder bridge could have a large camber (the Happy Pontist said aye). Today's steel bridge has an even bigger camber! Actually, this bridge is like one of those deck-stiffened arches designed by Robert Maillart (only made of steel instead of concrete).
As we saw yesterday, the bridge's handrail matches the railing used along the nearby paths and houses. However, no child could fall between the closely-spaced bars on today's bridge.
This is a nice area of Salisbury with pretty homes and a path along the river. We can see the Crane Bridge in the distance. I wonder if these huge homes were ever owned by a single family? I would imagine that today, four or five families live on every floor.

Technically, I think this one is an arch-stiffened deck.
ReplyDeleteFor a nice example of what can be achieved in tightly curving a very substantial steel bridge member, see the 762mm tubes curved to a 15m radius on the Coventry spiral bridge (http://www.betterpublicbuilding.org.uk/finalists/2004/glassbridge/). If they can bend that, then pretty much any precamber you can imagine is achievable. In the UK, there's at least one firm which basically specialises in pre-bending structural steelwork (http://www.anglering.com/).
