A new method which improves the fitting accuracy of artificial time history of ground motion to the target response spectrum by superimposing narrowband time histories in the time domain is proposed.

This month a game show will once again figure in the history of artificial intelligence, but this time the computer will be the guest: an IBM super-computer nicknamed Watson will compete on Jeopardy!

Appropriate artificial seismic time history is the basis of calculating earthquake action on tall buildings applying time history analysis method.
