Question

please read the article in online 'Understanding the Tragic Hyatt Regency Walkway Collapse' and explain about what went wrong in the design of the walkway found by the investigator and how was the change procedure wrongly communicated. Should be more than 300 words.

Answer 1

The article understanding of the Hyatt Regency walkway collapse depicts a tragic incident which took place in the Hyatt Regency Kansas City Missourie in July 1981. This non deliberate mishappening to place during a t dance being held in the lobby place. Two runways collapsed one over the other killing a good counts of people. It made the nation point out at the engineering ethics and mistakes alongside the disaster management abilities in the construction of the building. It was proved out to be a big failure. It was a multi storey Atrium in which four walkways suspending out from the ceiling and made the lobby look extra ordinary. The walkways were quite heavy and lied above each other in an alternative manner. The minor mistakes contributed to the huge disaster like the nuts were located at double sites rather than one alined vertically on a welded joint. The walkway had the minimum capacity to even support itself. It was a neglectful corporate culture which made the the design commit numerous architectural faults. The walkways were supported by a 1.25 mm diameter steel tie rods and the second Runaway lide directly below the fourth one. The fourth one comprised of three cross beams supported by the Steel rods held together by nuts. The C channel cross beams were hollow. There were three pair of rods which went to the ceiling through the second walkway and the force walkway and a nut benesth each tie rod that tightened up to the bottom of the second-floor walkway. this was done to hold the 4th walkway intact. In the original plan the weight the fourth walkway han to just be the weight of 4th walkway while the load of the second walkway was to be supported by the rods. However the revised design made the cross beams support the weight of both the walkways. Also the original design the bolts to be on the both sides of the box beam instead of top and bottom but the revised design made the box beam the weakest joint. During the tragedy, the box beam split into two half and the nut supporting them fell through the gap created and invited the tragedy.
Investigators concluded that the major problem was the lack of communication during the construction. The preliminary design was misinterpreted to be the final one . The associates were unable to review the design thoroughly and was accepted ahead without the necessary changes, calculations and reviews the major one being the overloading of the second and the fourth walkways. It was heavily criticized by saying that it was such an obvious flaw which could be figured out even by a first year engineering student
