I wonder why the case of continuous media, discussed in B&L, differs so dramatically? Can an upper block that has experienced 10x maximum elastic deformation of its lowest story stand on its own at one-third gravity? Seems reasonable. How about when it's going to get smacked one more time before the ride smoothes out?
Because we are talking about different types of collisions. An OODRD crush mode is very different from the column buckle/rebuckle mode upon which in B&V and B&L was formulated.
The column buckle/rebuckle/rebuckle mode of Bazant is pure fantasy. The argument in B&L that the upper block will remain largely preserved because columns cannot buckle upwards is meaningless. Basically he has a PhD and many people who couldn't understand the details in his argument beleived what he said without applying some simple reality checks, like studying the video evidence or looking at the resulting rubble.
OOSRD is the only known natural crush mode that matches all observables. If we size resistance to OOS floor to building connection strength rather than column strength, crush-up makes perfect sense.
