>I don't know the weakest point, the weld is stronger than the beam steel, generally.> I was hoping you would say the reverse. Then the explanation of sideways force would have made some more sense. If the the beam fails first, the pressure on the core column welds will actually decrease as soon as the beam failed and the weight of the rubble followed the weakest point. >I can see heat causing significant popping and cracking of the core as water boils out and then serious sideways force being applied to that core.> The heat does not explain the sequential failure of the column on every floor, With each lower floor, the heat got less, and the core column was designed to handle larger weights. -Arun
