Author Topic: Minneapolis Bridge Collapse Ben Wales Jedi Master Film Handler Posts: 602 From: Southampton. England Registered: Jul 99 posted 08-04-2007 05:46 PM                     One of the Oldest Contrete structures (may in the World) is not far from where I live and is call Sway Tower and still stands at 200ft!. "Sway is perhaps best known for Sway Tower. At 66 metres (200 feet), it is the tallest folly in the world. It is a Grade II listed building. It is also known as "Peterson's Folly" Built by Judge Andrew Thomas Turton Peterson on his private estate from 1879-1885, its design was influenced by the follies Peterson had seen during his time in India. It is constructed entirely out of Portland cement, supported by iron joists. At the time it was built, it was the tallest concrete structure in the world. It was originally designed as a mausoleum, with a perpetual light at the top. However this was not allowed, as it was thought the light would confuse shipping. The tower is visible from much of the New Forest, and most of the western Solent."  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 08-04-2007 07:02 PM                  quote: Louis Bornwasser Note that they were busy repaving a structurally bad bridge. Good point, Louis!  |  IP: Logged Dustin Mitchell Phenomenal Film Handler Posts: 1865 From: Mondovi, WI, USA Registered: Mar 2000 posted 08-04-2007 07:28 PM                     From what I understand the repairs that were being done were to the surface of the deck, or more specifically, the pavement. As far as I know-and I could be mistaken-no structural repairs were being done at the time of the collapse.  |  IP: Logged Jim Bedford Jedi Master Film Handler Posts: 597 From: Telluride, CO, USA (733 mi.

If if was substandard or weakened in the first place, then the activity and additional weight might have made the structural issues reach their tipping point. Monday, more than 100,000,000 Americans are going to cross a bridge that has the same rating as this one did before its collapse. Sort of like playing the wrong lottery, eh?  |  IP: Logged Chad Souder Jedi Master Film Handler Posts: 962 From: Waterloo, IA, USA Registered: Feb 2000 posted 08-05-2007 11:15 AM                     quote: Jim Bedford If if was substandard or weakened in the first place, then the activity and additional weight might have made the structural issues reach their tipping point. Actually, in my understanding, the ongoing construction kept a lot of weight off the bridge at the time of the collapse as there were only 2 lanes open for traffic as opposed to the "normal" 4 lanes. The construction could be a blessing in disguise as the number of cars was fewer and possibly at a stand-still because of it, although I am well aware that during that time of day there is regularly stopped traffic throughout the Twin Cities.  |  IP: Logged Jeremy Jorgenson Phenomenal Film Handler Posts: 1002 From: Chicago, IL, USA Registered: Feb 2005 posted 08-09-2007 06:00 AM                        When this happened, I checked google's satellite image of the bridge pre-collapse ... the water looks to be rough there. ------ ...speaking of cement, the new Trump Tower in Chicago (supposedly being completed in 2008 & will be Chicago's 2nd tallest building until about 2010) is using concrete (rather than steel) in order to fit the footprint it had available & still have the height.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 08-09-2007 09:31 AM                        Was that weir a little way upstream built to relieve the water pressure on the bridge supports?  |  IP: Logged Chad Souder Jedi Master Film Handler Posts: 962 From: Waterloo, IA, USA Registered: Feb 2000 posted 08-09-2007 03:15 PM                     Jeremy - Do you know when that picture was taken?  |  IP: Logged Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 08-09-2007 06:29 PM                     No supports for this bridge were in the water, supported from both banks.  |  IP: Logged Jeremy Jorgenson Phenomenal Film Handler Posts: 1002 From: Chicago, IL, USA Registered: Feb 2005 posted 08-09-2007 08:33 PM                        quote: Chad Souder Jeremy - Do you know when that picture was taken?
