Summary

DescriptionHRWalkway.svg	English: Connection details of a cross beam on the fourth-floor elevated walkway in theHyatt Regency Crown Center inKansas City,Missouri,United States. The failure caused the deaths of 114 people, injuring 200 more. It was the worst structural failure of its time (1981). (a) Original connection design; each nut takes the load (P) of one walkway (because the load of the NEXT walkway is transmitted through the single, continous steel rod, not through the nut) (b) Modified design (done due to constructibility issues) that ultimately led to thefailure of the walkway due to one nut having to bear the the load of two walkways (2P)
