>The core itself is a rather heavy chunk of concrete (strong in compression, weak in tension) and if the floor beams failed in such a way as to apply sideways tension on that core causing it to crack.....> So are you saying, that the core can take 50+ floors of weight and not crack for 30 years and it cannot take the shock of a vibrating beam that is shearing off with the weight of 1-5 floors of rubble from above floors any time? Is it not more likely that the floor beam that is just designed to take a few floors of rubble shears off the core at the welds/joints to the core and falls onto the next floor. This is assuming that the welds/joints are the weakest link on each floor and not the floor beam itself at a central point of the floor furthest away from the core. Once that happens there is practically no resistance to the falling rubble and it falls down the chute leaving little impact on the core column itself on that section of the floor. -Arun
