Re: [Assam] More on Minneapolis Collapse; Big Dig project
C-da, My suggestion is that please find sometime to guide students of architecture in India and US as a guest faculty atleast -sharing your world of experience after you graduation in 1969 from Architecture dept of IIT Kharagpur (where a student of mine is now sudying) . About Boston's failed Big Dig undersea-tunnel project (world's largest construction project) leading to Logan AIrport from Boston city -- which you explained so clearly here- I had never known its faults with even Harvard's and MIT's archi. schools around ( I went thru the tunnel only once in a shared taxi --while coming to DC for the first time with Harvard classmates in Nov 2004 for a edu. seminar of CIES ) You do have a knack of explaining things - tough teaching needs more patience than other activities. Best wishes.

But the premise of your questions left me completely bewildered. Did *I* make those assertions about the qualifications or even implied them about who might have designed the bridge, or how good they were in math? How do you know who designed it? What if it was designed by some very creative East Pakistani structural engineer trained at BE college, like Fazlur Khan, who developed the structural system for the Sears Towers? What then? I thought you are an engineer. But from the comments you make and the questions you ask, I must have been wrong. Anyway, a bridge's integrity is not the function of just its design alone. The math skills of the designer hardly enter the equation. Most structural elements fail not because of design, but for a variety of other factors, most notably due to poor construction practices , which is a result of incompetent management, human failures, sometimes corruption--as in India, and sometimes just because of the laws of probability playing out: if something could go wrong, it would, sooner or later. The Boston Tunnel concrete panel failures were determined to be a result of using quick-setting epoxy bolts, instead of the specified standard setting epoxy, which develop their full strength slowly, over about 48 hours, but remain strong thereafter. On the other hand the quick setting epoxy develops strength within minutes, but do not retain it over time. Investigators found, that the right material was ordered by the installers, but was furnished the wrong product by the supplier . It appears as though someone in the shipping warehouse packed the wrong stuff. Here it is a case of a human failure, that no amount engineering acumen or management expertise could have prevented. The Minneapolis failure seems to have been precipitated by huge amounts of dead weight piled on the bridge deck from rock sent for the repairs. This is a management failure. Whoever was overseeing the logistics of the material delivery either did not have any knowledge of structures and load bearing capacity of a structure or was asleep at the wheel. There could be other factors: Such as non-inclusion of the redundancy principle of design. This was a political issue, of managing the cost and funding. Or defective welding. Fifty years back welding technology was not as sophisticated as it is today. Today we have ultrasonic testing done, before welded structural members of critical components. In my last major project, I had to reject a number of large span bowstring trusses, which were shop welded, but installed without ultrasonic testing. The installers installed the trusses, but when asked for certificates of testing, could not produce them. On site testing showed that a number of joints were unacceptable. The result was a very expensive on site correction of the joints that cost the steel fabricators big time. By the end of the job, the fabricator was going out of business. Apparently it had other problems elsewhere as well. They got our job, because they were the lowest bidders, and not necessarily because they were also good fabricators. The public bidding requirements in this case was a contributing factor-- by allowing a fabricator of questionable skills or management abilities to get the work. The

It is still being litigated as the news-clip I posted earlier shows I will give you a small example: In the eighties, an interior bridge/walkway over the Lobby at the Hyatt Regency hotel in Kansas City collapsed from dancing and partying guests, killing hundreds. Next day structural engineers' and (architects' too) liability insurance rates shot up thru the roof, and has not yet come back down. For years I, a tiny operator, have been paying far more in liability insurance rates than a practising internist would be. I don't know who else had to pay or how. But that was a lesson not to be forgotten--about what it might mean to be sloppy with one's work. The highly respected structural engineering firm of course went out of business immediately. The top man, if I am not mistaken, fled the country. I don't know if he was ever brought to justice or what happened to him. But regardless, it changed the ways things are done, dramatically. Now you tell us how such a tragedy has changed Indian engineering or governance. Unless of course none such ever happened in India. Tell what institutional deterrence i there. It was only a couple of weeks back, the equivalent of the FDA director of China was executed, for taking bribes of less than a million dollar. It was a very severe punishment.

At any event, MOST structural design is not a result of creative engineering: they are dictated by standards and codes and budgets. Most day-to-day structural engineering in the USA is done not by highly skilled engineers, but by 'designers', who are vocational tech. school graduates with high school degrees, It was you who mentioned that Creative American Engineers contribute to Nation Building and Indian Engineers have zero contribution in Nation Building.

This is what a Mech,Engineer from Mass blogged in a CR4 Bridge Collapse blog: Posts: 32 #54 Re: Bridge collapse 08/06/2007 8:15 PM One comment I haven't heard or seen yet. Did the people who designed the bridge have a crystal ball to tell them that the politicians would take huge political donations (the political correct term for bribes and kickbacks) from the trucking companies and teamsters to lift the limits on what the weight limits for trucks can carry? I haven't checked on the real numbers yet but I know the limits are way up from the time when this bridge would have been designed. The bridge problem is the same as the war problem - The PROFESSIONAL POLITICIANS. DON'T RE-ELECT ANYONE.

Can Yours Truly add on? Saw this in a blog at CR4 site I comment in: __ And in that vein, I was talking to a compatriot the other day, and the topic of the 60's generation came up - it seems the same level of mistrust of government and general rebelliousness is still alive and well in the hearts of the baby boomers but the difference is now we're old and generally have more money than we did back then. Perhaps, it was suggested, we could finance our own revolution, outsource an army (since ours is busy every where else right now)to take back the government from the special interest groups, kick the parasites, demagogues, and criminals out of Washington, DC, and return our government to what it was originally meant to be. Something to ponder. Of course in this day and age it could get you rendered to a foreign country and tortured so if there are any HS agents out there watching this forum, it was all in jest and simply amounted to the ramblings of the pre-Alzhimers coalition over cups of weak coffee.

more from that Pandora's box: __ Join Date: May 2005 Location: Las Cruces, NM Posts: 48 #26 Re: Bridge collapse 08/05/2007 8:01 PM It is unfortunate that this post duplicates a similar post under Civil Engineering: http://cr4.globalspec.com/thread/10774/Could-bridge-collapse-be-prevented?frmtrk=CR4digest I repeat my post from that thread: There are many reasons why bridges collapse. They mostly fall into two major categories: (1) compromised maintenance, (2) unanticipated features of a new design concept. The history channel has prepared an excellent non-technical review of the recent history of bridge collapses http://www.history.com/minisite.do?content_type=Minisite_Genericcontent_type_id=55377mini_id=1335 Regarding the second: It is hard to argue against new designs, but since much of the concept polish in engineering is based on lessons learned (from disasters), we should at the very least recognize that there is significant inherent risk coupled with every departure from the tried and true. New concepts are thoroughly investigated by a modeling, but the models only evaluate the problems which we can think of, and often they cheat by adding complexity (tweakable knobs) so that modelers can tune their models to compensate for things that they cannot resolve intellectually. This subject is treated at length in an excellent book: The Future of Everything: The Science of Prediction by David Orrell As to the first: A call to action was issued following the collapse of the Silver Bridge over the Ohio River in 1967 citing to inattention that we pay to our infrastructure. This call has been repeated after each ensuing collapse and is soon forgotten. Politicians play to the whims of the voters, which they skillfully manipulate. Politicians readily decide to spend a trillion dollars on a ill advised war, but can never find funding for basic human needs (education, health care, infrastructure, etc.). It's not their fault: we (re)elect them and put up with their fanciful tirades.

How much gasoline, diesel and jet fuel does the services consume in a week? Where does that money go? Mostly to OPEC nations for oil at $60 to $75 a bbl. How much of these fuels can be made from a bbl of crude? How much aid, in many forms, do OPEC nations contribute to the enemy in Iraq and Afghanistan? How much of that is paid for with our oil money to OPEC nations? How many terrorists does Saudi, Iran, Syria, et al train, equip and support? Are we accomplishing any good in Iraq? Is Iraq any better off now that it was 20 years ago under a dictator? How many lives of US service personal is that accomplishment worth? What price does one put on a young, vibrant human life?

They mostly fall into two major categories: (1) compromised maintenance, (2) unanticipated features of a new design concept. The history channel has prepared an excellent non-technical review of the recent history of bridge collapses http://www.history.com/minisite.do?content_type=Minisite_Genericcontent_type_id=55377mini_id=1335 Regarding the second: It is hard to argue against new designs, but since much of the concept polish in engineering is based on lessons learned (from disasters), we should at the very least recognize that there is significant inherent risk coupled with every departure from the tried and true. New concepts are thoroughly investigated by a modeling, but the models only evaluate the problems which we can think of, and often they cheat by adding complexity (tweakable knobs) so that modelers can tune their models to compensate for things that they cannot resolve intellectually. This subject is treated at length in an excellent book: The Future of Everything: The Science of Prediction by David Orrell As to the first: A call to action was issued following the collapse of the Silver Bridge over the Ohio River in 1967 citing to inattention that we pay to our infrastructure. This call has been repeated after each ensuing collapse and is soon forgotten. Politicians play to the whims of the voters, which they skillfully manipulate. Politicians readily decide to spend a trillion dollars on a ill advised war, but can never find funding for basic human needs (education, health care, infrastructure, etc.). It's not their fault: we (re)elect them and put up with their fanciful tirades.

How much gasoline, diesel and jet fuel does the services consume in a week? Where does that money go? Mostly to OPEC nations for oil at $60 to $75 a bbl. How much of these fuels can be made from a bbl of crude? How much aid, in many forms, do OPEC nations contribute to the enemy in Iraq and Afghanistan? How much of that is paid for with our oil money to OPEC nations? How many terrorists does Saudi, Iran, Syria, et al train, equip and support? Are we accomplishing any good in Iraq? Is Iraq any better off now that it was 20 years ago under a dictator? How many lives of US service personal is that accomplishment worth? What price does one put on a young, vibrant human life?

Re: [Assam] More on Minneapolis Collapse-- A Quick Primer
http://www.nytimes.com/ref/us/20070803_BRIDGE_GRAPHIC.html#step1 This shows some possible problem sources. I am no structural engineer, but I know enough to be dangerous :-). If I had to bet on as single cause, it will be on No: 6. And if I were to second guess on judgement, it will be on 8. St. Louis has 12 bridges on the Mississippi and the Missouri. All of them have redundancy built in, to some extent. There was a major bridge collapse on the Ohio river I believe , which also had no redundancy built in. Why does anyone need redundancy? Because these structures have many components and their integrity depends on many many factors. So one cannot put all the eggs in one basket, betting that everything would have been built as designed or wished. For that does not EVER happen.

Maybe, they came to the USA to make more money (read better opportunities). While, I do not think there is anything wrong with that, let us realize that there are many many people in India who are just as capabale or better than immigrants to the US and who have contributed to Indian's growth and development. Third, if these people were not creative in India, how is it that these very same people with the basic fundamentals from India have suddenly become creative here? Did they suddenly sprout wings? Lastly, (and I may the loner here) - Math science are great, but let us not put down other branches.
