This theory was contributed by Tom Martin and IA Mcleod-they investigated the disaster using the modern computer analysis techniques in the light of modern approach to wind loading. A meticulous monitoring and maintenance schedule should have been followed considering the fact that the bridge was taking heavy traffic and high winds. The Tay Bridge Disaster as the incident is popularly known , was one of the worst structure failures of the time both in terms of the size and significance of the structure and also was one of the biggest disasters as it took lives of 75 people.

Although it would have taken major change in designing the bridge for higher wind load such things like the size of the abbot other bases of the pier were also compromised which could have had (and eventually had) vital impact on the safety of such an important structure.

Identify and analyse the requirements with particular reference to viability and safety of project.

In the discussion the causes of failure have been identified and analyzed in detail.

We know from the recorded information that at least two piers of the Tay bridge which fell into the river and were damaged during the construction were straightened and reused. The Tay Bridge disaster occurred during a violent storm on Sunday 28 December 1879 when the first Tay Rail Bridge collapsed while a train was passing over it from Wormit to Dundee, killing all aboard. If you need assistance with writing your essay, our professional essay writing service is here to help! It was found that at least two piers fell while construction and were used after the repair/straightening. Nick named Galloping Gertie, owing to its twisting and rolling behavior, designed by Moisseff who put solid steel girder beneath the road way to strengthen it, which were found to blocking the wind and causing the bridge to twist the defect in design (but the safety was not intentionally compromised) lead this massive structure to collapse on 7th Nov 1940 just 4 months after its opening.

Reference this. An enquiry was entrusted to three judge court who were helped by two experts. In cases of huge projects like “Tay Bridge”,it is a common practice before initiating a project to check for its viability taking help from the professional consultants and it is not uncommon to have second opinion and even involving more than one organization in the role of conceptualization and the design. How the disaster happen’d on the last Sabbath day of 1879, Which will be remember’d for a very long time. In fact we have many reported structural failures occurring even today because of compromising the safety and bad and unethical practices-, In the recent Potters Bar Accident-10may2002-the cause of the derailment of the last coach of the passing train was ascertained as-poor maintenance ,leaving the bolts on points near the station loose. It had been operational for almost two years. According to the theory it was the derailment of the train caused by a kink and the force of the overthrown carriage produced the impact that triggered the fracture of the lugs connecting the braces leading to collapse of the pier structure. Universities, industry and the institutes and organization related with industry such as Institute of Chartered Civil Engineers should work on this in a co-ordinated manner. In short, I think that the rear carriages of the train derailed and ran into one of the cover paltes. In order to investigate and analyse the engineering failings we shall discuss all these theories in brief:-. -they paid special attention to the cast iron lugs(which were twisted, fractured and broken see photo-1.3 & 1.4 ) which secured the braces and the nuts and the bolts (that were lying fractured)by which the braces were secured. Mainly because of the scale of the disaster but also because of the BOT inquiry which gave a detailed account of the failure but fell short of specifying how exactly the final collapse of the high girder section occurred leaving a mystery to be unraveled. And the structure was repaired improperly without informing the competent authority. In the discussion the causes of failure have been identified and analyzed in detail. Need to stay on course.

But the design was not compromised in the case neither any bad practice or ethics was involved. And down went the train and passengers into the Tay! That the “fall of bridge was occasioned by the insufficiency of the cross bracing and its fastenings to sustain the force of the gail”-see photo-1.4. Registered office: Venture House, Cross Street, Arnold, Nottingham, Nottinghamshire, NG5 7PJ. The court announced its finding in record six month time holding Bouch ,the designer responsible for the incident who was ripped of contracts for design for Forth Bridge and died a few months after the report of enquiry was made public.

Creativity and innovation is the key to advancement and growth of any industry, but this should be encouraged during the conceptualization and design stage when the new idea, practice or material can be fully tested in real as well as simulated conditions. We've received widespread press coverage since 2003, Your UKEssays purchase is secure and we're rated 4.4/5 on reviews.co.uk. It must have been an awful sight, To witness in the dusky moonlight, While the Storm Fiend did laugh, and angry did bray, Along the Railway Bridge of the Silv’ry Tay, Oh! Company Registration No: 4964706. He had also won the contract for the Forth Bridge which was later cancelled as a consequence of the disaster and findings of the enquiry. Talk about the likelihood of any compromises to safe design and construction occurring today and suggesting safeguards to prevent such practices. Ethics discouraging bad practices should be encouraged, inculcated and incorporated in the professionals both at the academic and professional stage.

However, we should not blame the designer for a low safety factor as the safety factor of 4 or5 was the norm then.

It took six hundred men six years to build the bridge. Final design of First Quebec Bridge Figure 7.

Registered Data Controller No: Z1821391. In the words of Bill Dow, retired lecturer in physics, the proponent of the theory-“Although there were probably many things involved, I believe that this derailment played a key role in the fall of the bridge. *You can also browse our support articles here >. As the train reached the “High Girders” as they were called both train and the bridge were swept down to the Estuary, no soul survived the incident. It was designed by Sir Thomas Bouch who had a reputation for designing cost effective bridges. We cant leave the responsibility of human lives in the hands of one person (as was done in the case of Tay bridge) or in the hands of single organization as is the common modern practice in many cases.

We know that it was the force of the wind that caused the bridge to collapse. It is the general purpose of this study to acquaint the reader with ... especially in the case of foundation failures. The incident left 6 people dead and many injured.” -. Certifying/ passing authority should share the responsibility for the failure. What they intend to propose is the collapse mechanism-an exact sequence of events that occurred on the fateful night, the point which was not made very clear by the enquiry. They used the mathematical model -“three dimensional elastic frame computer model”-based on engineering drawings, court of enquiry report, Henry law report and results of component testing by the court of enquiry for testing the wind loading, to arrive at the conclusion that when the train reached the high girders the strong gust of wind created the upward lift uprooting the base of the windward side of the column which forced the diagonal tiles to fail at level 2 triggering the failure of the braces upward.
