A structural engineer is quoted in the article that this uneven strut design would have worked if if that end beam was more solid.
- Paperweight 8y agoIt still bugs me. Yeah, that part would work, at least until it got loaded weird by high winds or by being hit by a truck or something. They were very unconventional in this design (new type of concrete, single row of struts, prefabricated construction, concrete instead of steel, uneven struts, computer-only analysis instead of civil engineering 101 static analysis) that it demanded extreme care. Conventional bridge design patterns are robust as in they still work when they're old, under unexpected loads, analyzed by below-average engineers, or built with less-than-perfect materials. Deviating from them demands extra extra care, or people die. :/
- 21 8y agoAs you said, the problem was not necessarily the idea, but that they were not careful enough. I'm sure you noticed that sky-scraper shapes are getting weirder and more unstable-looking: https://www.designbuild-network.com/wp-content/uploads/sites/21/2017/10/1-capital-gate-hotel.jpg https://www.designbuild-network.com/wp-content/uploads/sites...
