The Hyatt Regency Walkway Collapse was a catastrophic event that occurred on July 17, 1981, at the Hyatt Regency Hotel in Kansas City, Missouri. The disaster claimed the lives of 114 people and injured over 200 others, making it one of the deadliest structural failures in U.S. history.
The collapse occurred during a tea dance event at the hotel, where hundreds of people were gathered on the fourth-floor walkway that connected the hotel's atrium to its lobby. The walkway was suspended from steel rods that ran through the atrium and were anchored to the ceiling above. However, due to a design flaw, the rods were not strong enough to support the weight of the walkway, and as a result, the structure collapsed, causing the walkway to plummet onto the lobby floor below.
The disaster was caused by a combination of factors, including a lack of proper oversight, inadequate design and engineering, and poor construction practices. The design of the walkway had been modified multiple times during the construction process, and the final design did not meet the required safety standards. Additionally, the steel rods that were used to support the walkway were not properly anchored to the ceiling, and the bolts that were used to secure them were inadequate.
The aftermath of the collapse was chaotic and devastating, with rescue workers struggling to reach and extract survivors from the rubble. The disaster had a profound impact on the city of Kansas City, as well as on the wider engineering community. In the wake of the collapse, a number of investigations were launched, and numerous lawsuits were filed against the hotel, the engineering firm responsible for the design of the walkway, and the construction company that built it.
The tragedy of the Hyatt Regency Walkway Collapse serves as a reminder of the importance of proper oversight, design, and construction practices in ensuring the safety of public structures. It also highlights the need for rigorous testing and inspection to ensure that structures are able to withstand the forces they are subjected to. The disaster had a lasting impact on the engineering community and led to a number of changes in design and construction practices, helping to prevent similar tragedies from occurring in the future.
Hyatt Regency Walkway Collapse: 114 People Were Killed
For the appearance effect, Jack D. The serious flaws of the revised design were compounded by the fact that both designs placed the bolts directly through a welded joint connecting two C-channels, the weakest structural point in the box beams. It helps engineers for modeling, drafting, and processing complex calculations. Retrieved July 17, 2019. They lost their engineering licences in the states of Missouri, Kansas and Texas along with their membership with ASCE American Society of Civil Engineers. The team included members from the Fire Brigade, EMS units, and doctors from five local hospitals.
In addition to the reports, meetings were held between the owner, architect and G. Retrieved July 14, 2021. May 5, 1983 Principals Jack D. The technical element is that the designers chose the most fragile box girder structure for a stunning effect. For purposes of this case study, we assume that the disputed telephone call was made by the fabrication firm and that the engineering firm did give verbal approval for the fatal design change. The contract was standard in nature, and Gillum-Colaco, Inc. Mark Williams, the last person rescued alive from the rubble, spent more than nine and a half hours pinned underneath the lower skywalk with both of his legs pulled out of their sockets.
Both walkway then fell to the ground killing 114 and severely injuring over 200 persons. The style and design look great though! This design change would be fatal. Therefore, the maxim cannot be universalized because it raises a contradiction. Thus the design load acting on the upper portion of a continuous hanger rod would have been twice that acting on the lower portion, but the required design load for the box beam hanger rod connections would have been the same for both walkways 20. Retrieved October 10, 2011. Thus the ultimate capacity actually available using the original connection detail would have been approximately 60% of that expected of a connection designed in accordance with AISC Specifications. Bernhardt, 2016 According to Jack D.

July 1980: Construction of hotel complete, and the Kansas City Hyatt Regency Hotel opens for business. Ultimately, it was concluded that the failure of the walkways were attributed to the fact that the construction did not meet the Kansas City Building code requirements coupled with miscommunication within the project between designers and constructors Stalking the Causes of the Hyatt Tragedy 1981. The fabricator changed the design from a one-rod to a two-rod system to simplify the assembly task, doubling the load on the connector, which ultimately resulted in the walkways collapse. An Engineering Disaster In conclusion it is necessary to outline that the Hyatt Hotel tragedy is a classic example for students being taught engineering errors and ethics. Havens agrees to fabricate and erect the atrium steel for the Hyatt project. This only makes a difference on the hanger rod nearest this support it would carry less load than the others and would not govern design.

They should have been aware of how their negligence was reflecting on the wider society of the engineering community and by their own negligence they were encouraging the practice of negligence within others. AR840239 hereinafter referred to as Administrative Hearing Commission. Without being too graphic, fatally injured victims were given morphine to ease their pain, and rescuers were even required, at times, to The fallen bridges weren't the only issue. As a result, the owner called in the inspection team. The volume contains both the findings of the case and an exce l ent general discussion of responsibilities of the professional engineer.

Subsequently, Duncan and Gillum lost their licenses to practice engineering in the State of Missouri, and G. Gillum and Associates and other units.
Retrieved July 14, 2021. Investigators concluded that the basic problem was a lack of proper communication between Jack D. This design was to prove fatal. Radio station KJLA would later earn a National Associated Press award for its reporting on the night of the disaster. The collapse killed 114 people and injured more than 200. Retrieved May 4, 2020.

Their contract dealt primarily with the investigation of the cause of the roof collapse and created no obligation to check any engineering or design work beyond the scope of that investigation and contract. Havens therefore proposed an alternate plan in which two separate sets of tie rods would be used: one connecting the fourth floor walkway to the ceiling, and the other connecting the second floor walkway to the fourth floor walkway. Structural Failure During the Atrium Tea Dance In 1976, Crown Center Redevelopment Corporation initiated a project for designing and building a Hyatt Regency Hotel in Kansas City Missouri. On or about December 19, 1978, Eldridge Construction Company, the general contractor on the Hyatt project, entered into a subcontract with Havens Steel Company fabricator who agreed to fabricate and erect the atrium steel for the Hyatt project.
