Stedfastly Refusing to Learn – Russian Edition

In engineering certain problems are only obvious after they’ve happen, put brutally someone has to make the mistake before anyone knows there is a problem. This is unfortunate but a fact of life. However after the new problem emerges, is publicised and even turns up in secondary school lessons as the classic example there is no excuse whatsoever for making the same mistake again.

Today’s example of this steadfast refusal to pay attention is; The Volgograd Bridge. If the scene of a wildly oscillating bridge looks familiar, that’s probably because it looks a lot like the Tacoma Narrows Bridge, which happened in 1940. And it’s not even like Tacoma was a one off freak, half a dozen or so bridges had excess movement and those were just the reported ones, countless others fell over but weren’t caught on camera so aren’t famous.

Now admittedly it’s one of the longer bridges in Russia, but by international standards it’s nothing special, indeed there are even bridges in Russia that are almost twice as long. There really is therefore no excuse for making such a bugger up unless there is something fundamentally wrong with your design and engineering culture. Mind you that’s probably a given as it took 13 years to build it, even in bad conditions that was at worst a five year job, indeed as the second bridge (for the other carriageway) isn’t open yet it is technically took “13 years and counting” to build.

I have saved the best till last, after this embarrassing mistake what has the reaction been? They closed it for a few days to check it out, but have now re-opened it with a clean bill of health and without modification, save for one change; a monitoring system to close the bridge if it gets windy! If that isn’t a vote of confidence I don’t know what is. This will end in tears, mark my words.
