LAY man's SAY

Sam Lee's article just exemplifies the revolution in architecture.It is not the culmination of evolution of Technology, yet ,man's ambition is audaciously undeterred to challenge even Mother Nature. I am overwhelmed at the fact that we have the technology to actually put Non Linear Dynamic analysis to use .In fact,it is being used in some very important upcoming buildings as mentioned in the article. Although the calculation discussed in the article is beyond my reckoning, I have strove to understand the gist of the article and the importance of it.I would really like to understand more about it from a lay person's perspective. I had expected to get an idea about the sequence of the steps involved in using Non Linear Dynamic analysis but I am afraid I didn't quite follow that. I would also like to question Sam Lee that how safe the already built skyscrapers of USA and other countries are and what could be done to make them safer and more stable to earthquakes.
