The failure of a structure is described as the propagation of local collapse from one segment to another segment, eventually resulting in the failure of an entire building or its lopsided part. The corrosion of the rebar in the slabs, as revealed in the 2018 report, was probably significant only if it occurred in places where the slabs joined with the columns, Mr. Dusenberry said. In such collapses, a local failure is followed by widespread collapse through a chain reaction.
