Does “Galloping Gertie” translate into Chinese?
Chinese engineering expertise is matched only by their medical expertise...
Does anyone know how old this bridge is? From the pictures, it looks like a conventional suspension bridge, but in such situations I always wonder if the architects and engineers were trying anything new. China’s development has been remarkable in recent decades and stunning new buildings and bridges have become common. As far as I know, the safety record has been good, but mistakes can happen when people start chasing novelty.
They are supposed to do that but it stresses the bridge so it comes down to engineering,material and workmanship. Many American bridges have simply fallen.
I guess they didn’t take into consideration the dynamic harmonic effect of the vehicles crossing.
Way back in the olden days when they would build concrete roads/state highways the concrete would be poured in rectangular panels so the joints were perpendicular to the centerline of the road. So when you drove you car it would go flump, flump, flump, flump...etc., as you drove. This wasn’t a problem with the cars prior to the 50’s. By then as cars were getting bigger, faster, and suspensions systems changed it became a problem as a car would developed a harmonic balance from constantly driving over these joints and it would cause the car to actually go off the road. This was referred to as the Buick hop.
Modern concrete roads have diagonal joints so the tires on the front axle or tires on the rear axle are not crossing their respective joints at the same time.
I wish you people would cease linking to sites that forbid adblockers. You’re pandering to the enemas.
That just ain’t right.
Like their buildings that fall over or walls that peel off.
Or the drywall they sent to the USA that was toxic.
Or the virus they send.
