So far in corners of apartment blocks and a cafe type place near the cultural center, which is also increasingly deteriorating. There is a growing debate in past 2-3 years among those who want to raze the whole city and those who want to preserve it as a historical site. our scientific "experts"(sic) claim there is no relation to the near miss and the events in Russia, Cuba and California although events like this appear to happen in clusters. I happen to believe in the theory that we are overdue for several more larger events in the near future including major earthquakes/volcanic activity in US and in a larger meteor strikes. We've been fairly quiet these past few hundred years. ragingbull Member send PM   block PM add to buddies Send: 2/19/2013 1:05:53 AM   This is what Mr. Durak defends. Your kid will grow up like you. Many enemies. Makes up stupid racist things.

Durak, its rater frightening thinking of it, but i would think there isnt a problem of such today, other then North Korea or maybe some Arab state pulling something stupid from such. but in the time when the cold war was at its height,, we were very lucky i think. i am still amazed and puzzled of those events that took place back then, and i saw some of it,, bureaucrats have a lot to answer for... durak Member send PM   block PM add to buddies Send: 2/20/2013 11:27:59 AM   @kiwi: According to wikipedia, "Pripyat was founded on 4 February 1970," so no building there is much older than 40 years. I've long had the impression that Soviet-era housing construction was very shoddy indeed. One tragic example was an earthquake (in Armenia, if memory serves) near the end of the Soviet era, in which the typical concrete apartment blocks collapsed like houses of cards. In part -- as you observed about the poor quality of mortar -- this was probably due to material shortages, which were a permanent condition in the Soviet planned economy. I suspect that the post-Soviet buildings have been gradually approaching western European standards, and will show better durability. ________________________________ About the problem of "accidental nuclear missile launch" -- I certainly HOPE that this has much reduced, but probably it hasn't gone away. I've climbed down into an active ICBM silo, mindful of the warhead sleeping a few meters away. It would be sensible for the world's nuclear missile forces -- I can think of perhaps four countries that would really have such -- to be on less of a hair trigger than during the cold war. But the warrior mentality can deviate far from sensibility. One scary example, which I learned about only a few years ago, has to do with a safety device that was added to all US nuclear warheads in the 1960s called a Permissive Action Link. It requires manual entry of a code in order to activate the warhead (this is not the same as the codes required to order launching a missile or dropping a nuclear bomb, which would be sent remotely). The idea was that if a warhead were stolen, lost in transportation, etc., the PAL would make it much more difficult to set off without knowing the code. Well, Gen. Curtis LeMay, then head of the US ICBM forces, was so contemptuous of this safety measure, that he ordered all of the PALs configured so their code was all zeros. LeMay was what Freeman Dyson would have called "a typical pre-scientific military man, brutal and unimaginative." We can only hope that the present generation is more enlightened. durak Member send PM   block PM add to buddies Send: 2/21/2013 1:38:41 PM   More about Soviet construction quality... I was thinking about the roof collapse at the zinc factory in Chelyabinsk. The overpressure estimates I have found range from 0.7 to 1.4 lb/in^2 (psi). These are very high loads, ranging from 100 to 200 lb/ft^2 (psf). In terms of wind loading, 200 psf corresponds to 280 mph, probably higher than ever occurs outside a tornado. In the 19th century, British civil engineers standardized on 56 psf (148 mph) as a design criterion for wind loading -- probably a good figure for a region that is not prone to hurricanes or large tornadoes. (Britain is actually quite prone to tornadoes, but they tend to be small and with *relatively* modest wind speeds.) But roofs probably aren't designed on the basis of wind loads, which are assumed to come horizontally. On the other hand, a Siberian roof must withstand snow loading, and 100 psf can probably be reached with less than 5 feet of snow cover. Chelyabinsk is fairly far south in Russia -- I didn't find out how deep snow usually gets there. Most of the physical damage looks to have been broken glass, window frames pushed out of their openings, or doors/panels blown in. On that basis, my amateur assessment is that the buildings in Chelyabinsk performed well. But the zinc factory (which certainly looks too old to be post-Soviet) probably wasn't as strong as it needed to withstand a really snowy winter. We can be confident that a Tunguska-sized event over a city would have flattened a large percentage of buildings -- it would have resembled Hiroshima in September 1945. kiwinorth Member send PM   block PM add to buddies Send: 2/21/2013 4:24:20 PM   More about Soviet construction quality... when in eastern russia i had a conversation over a man who didnt look the full quid i took a interest in. i was told by his naighbours he was in charge of a build, an apartment block once. from what i understand a lot, or most of the apartments had been issued to people(or how ever it went) so they were in wait of completion. well the apartment block was found to have some very sh*tty workmanship. people became very angry, the workers were confronted, they didnt want a bar of it, so they told the angry crowd their boss was not giving them the right amount of cement and such for the job, also someone let the cat out of the bag and said he was selling the allocated cement and pocketing the money. certain persons from the crowd came back and confronted him i think at the building site, beat the shit out of him, hospitalized him for a very long time. his brain injury's were occurred from the beating. wants a bet the apartment wasnt pulled down and started over.. durak Member send PM   block PM add to buddies Send: 2/21/2013 5:18:14 PM   Wow kiwi, about what year was that? lonelyranger1701 Member send PM   block PM add to buddies Send: 2/21/2013 11:43:57 PM   The term for the kind of work you guys are talking about is “shoddy” !! Poor materials, inexperienced workers and low standards. During my travels over there, I’ve seen a lot of shoddy work. On my way between Kiev and Sumy, I was looking at the stone and cement homes along the road, trying to guess how old they were? My guess was about the turn of the century,,, the previous century,,, then I saw 1982 over one of the doors of a home. Stones and blocks missing, big cracks in the walls. Some of the homes looked abandoned,, but most were being lived in. While dining at a buffet style café in Tver’, I was watching TV with constant advertisements playing. Many were from contactors showing their work. It was awful!! Cement block or brick buildings,,, big gaps in the joints, none of it was finished off either. It looked like the work of amateurs and this is what they were advertising. One reason for knowing this, is that one side of my family has at least three generations of masons. I never worked with them much, but helped a little when they did work for us. In the northern half of my county, all of the masons that are in business today, got their start working for my cousins. kiwinorth Member send PM   block PM add to buddies Send: 2/22/2013 9:49:20 AM   Durak, i was told but my memory, i'm thinking maybe 10-15 years at the most after the cold war-ry thing. i couldnt imagine it been later for this area has lost way over half its population. theres quite a few apartment blocks unfinished due to the population collapse, they are just sitting shells. seems this city survived on the armed forces and once the cold war ended so did a lot of income. this is Sovetskaya Gavan i am speaking of. Hey Danny, you are a good bugger alright,, how many would let their inlaw go that far:) bloody good laugh but yeah when you think about it, that plant had some real stupid design faults. even in its time it was very questionable.. ragingbull Member send PM   block PM add to buddies Send: 2/22/2013 11:22:57 AM   How about their housing? I guess they are called flats. They look well built to me.
