(ignoring earthquakes) I guess the swimming pool would need to be on bearings and allowed some degree of rotation/translation from the buildings. This would be achievable as it does not extend that far into the building, so you should be able to have it supported in this way with a sliding bearing at the supports. I would not be surprised to see further supports and beams added to the initial architectural concept though. |

Um, yes. The Golden Gate Bridge had a big stiffening retrofit in the early 1950s, with huge rectangular frames added underneath.
As for putting in bearings, the SF Bay Bridge west span was given bearings after the 1989 quake. (The east span was totally replaced.) The roadway was jacked up at each tower, and big stainless steel plates inserted so the roadway could slide relative to the tower if necessary. Plus, 17 million pounds of structural steel and half a million high-strength bolts were added, so the roadway is strong enough to slide under extreme stress without coming apart.
And that's steel, which has reasonable elasticity. Glass, not so good at that. Is it really glass, or polycarbonate? Polycarbonate has some stretch; you can bend it in a sheet metal brake and it won't crack.
