So unless it is a very long gap that needs to be spanned like Golden Gate Strait or the Strait of Messina, which would require a suspension bridge , the cable stayed type will be the "go to bridge"
Source: personal experience. I have built 2 such bridges before. Led the planning and installation of the actual stay cables. I know all about it :-).
Had to make a lot of the jigs ourselves. Lots of room for innovation and automation ;-)
Any chance we can talk about your work, and perhaps specifically about the room for innovation and automation?
What about buckling though? With all that force from the cables pulling the bridge deck toward the towers, it seems like a bit of unexpected bending or weakness (breeze, earthquake, minor damage) could cause the deck to travel inward to the tower while being crushed.
I do have to agree that I am tired of cable-stay bridges. They are a distant third for looks, behind suspension and obviously the stone arch. More stone arches please! Do a big one, a mile or two in height.
Actually there is very little stress on the cables. The cables are stressed just enough to take the sag out of em. i.e. All the cables are actually supporting is their self weight! All you need is a hand-held jack and a lot of clever math, to install them :-).
The deck on one side of the tower is held in place by counter weight of the deck on the other side.
About earthquakes, it's designed for those 100 year quakes, hurricanes and floods. When we were building the Audubon Bridge across the Mississippi River, we were in fact hit by a 100-year flood and 2 hurricanes. Other than some stored material floating away and having to watch out for alligators in odd places. We got through fine :-)
The bridge type is rarely chosen for beauty :-) especially when contractors have to bid competitively for tonget a chance to build them. Governing factors are technical feasibility (design and constructability) and cost.
I live with a view of the bridges, it has been fascinating watching them construct the new bridge.
In fact, it is designed with enough redundancy that if lightning or an accident takes out 2 (maybe 3 , can't remember) of the cables, the bridge will still stand.
