Hyatt Regency: Why One Failure Took Both Walkways
About this video
In this structural failure investigation, we examine the Hyatt Regency Kansas City walkway collapse of 1981, focusing on the fatal connection that caused the fourth-floor walkway to hang from the wrong nuts. You'll learn how a simple design change doubled the load on a box-beam-to-hanger-rod connection, leading to a progressive collapse that killed 114 people. We break down the mechanism step by step, from the initial failure to the cascade that brought down the entire structure.
