How many buildings were built that had the weight of the structure supported in the outer columns and not the inner core ?
Did you even realise that the building design was very very different to others ?
Do you understand how and why the floors pancaked ?
How much strength is lost when you heat structural steel to 500 deg C?
Science helps you find the truth .
