J’oubliais ce passage :.

The steel-glass façade was completely destroyed, exposing the concrete perimeter columns. The steel columns above the 17th floor suffered complete collapse, partially coming to rest on the upper technical floor.

Preliminary findings suggest that a combination of the upper technical floor and the excellent passive fire resistance of the tower’s concrete columns and core prevented total building collapse.

The fire is significant in terms of its potential similarities between the collapse of the building’s steel frame above the 17th floor and the experience seen at the World Trade Center. Notably, one of the recommendations of NIST’s interim report on the World Trade Center disaster is for tall building design to incorporate ’strong points’ within the frame.

Voilà voila...
