Dru Posted September 21, 2005 Posted September 21, 2005 isnt that the one what fell down in the 1940s? history will repeat. Quote
Dru Posted September 21, 2005 Posted September 21, 2005 that first one gives lummox avatar pic a run for the money! Quote
catbirdseat Posted September 21, 2005 Posted September 21, 2005 What I don't quite understand is why they tore out the towers on the original bridge instead of reusing them. The problem with "Galloping Gurdy" was that its bluff sides caught the wind and it oscillated harmonically with increasing amplitude until it failed. That wasn't a function of the tower design. Perhaps the towers were damaged or it was not certain whether they were or not? Quote
bwrts Posted September 21, 2005 Posted September 21, 2005 Because that is what we do in America. Tear the old sheit down and replace with modern ("better") designs. Usually because technology has advanced in materials, but also because we need new projects to keep the machine running. Having a catastrophe is sometimes the only way big business can kick start a new project. Perhaps this will be the only way to fix the viaduct...when it falls down from an earthquake or on its own.

From what I have read, there was also a problem with the narrowness of the roadbed being partly to blame for the oscillation. Wider roadbed would require wider space within the tower. Quote

CBS - your answer is about four pages forward. The new bridge was heavier and had wider spacing of the main support cables - thus the need for new towers. -kurt Quote

billcoe Posted September 22, 2005 Posted September 22, 2005 Nice pic lucky, thanks for sharing! Quote
LUCKY Posted October 15, 2005 Author Posted October 15, 2005 Over a dozen strands of the big cable have been strung accross the narrows Hard work ...nice view going 6/10 hour days two shifts I will send you a good pic as the cable spin'n gets larger LUCKY Quote
LUCKY Posted October 16, 2005 Author Posted October 16, 2005 Here's is a link. http://seattletimes.nwsource.com/cgi-bin...p;date=20051015 I will send you a pic from the top of the east Tower later. The press don't seem to like the long climb up to the top or being that high up. Quote
MPaul_Hansen Posted October 21, 2005 Posted October 21, 2005 RE: New suspension bridge - Design should be recognized as an art. Pushing beyond known boundries can carry risks. Note the sides of the existing bridge are open trusses that allow wind to pass through, [rather than a buff face] and not permit a "shedding vortex" situation that led to increasing torsional occiliations, and then galloping. The truss work under the existing bridge is sort of box-like so it is not so prone to twist due to aero-elasticity effects from wind. Many highly technical references in the UW Engineering Library for those who wish to examine the nitty-gritty details regarding the collapse. PS I do not go on the Seattle Viaduct and have advised my friends to like-wise avoid the damaged structure. Quote
JoshK Posted October 21, 2005 Posted October 21, 2005 The Alaska Way Viaduct is a time bomb just waiting to kill people. God willing when it DOES collapse (not if...when) it will happen in the middle of the night and not rush hour. When it does kill people, it could arguably be a case of criminal neglect. I think the building codes in Burma are better than the ones that thing are built to. Quote
LUCKY Posted October 21, 2005 Author Posted October 21, 2005 PS I do not go on the Seattle Viaduct and have advised my friends to like-wise avoid the damaged structure. Pass the gas tax and let's build a new one How are any of you going to feel if a friend, co worker or relative gets crushed by the old one, if you vote the gas tax down? The price of gas is sooo high right now from the oil barons making windfall(and that is a pun) $$$$$$$$ Quote
skyhigh Posted October 22, 2005 Posted October 22, 2005 How are any of you going to feel if a friend, co worker or relative gets crushed by the old one, I think that would depend on which friend, coworker or relative....or at least which side of the family. Quote
LUCKY Posted December 3, 2005 Author Posted December 3, 2005 white powdery substance on cables 12 strands of 38 total are now accross the narrows LUCKY Quote
