| Research Abstract |
Herein the study, first we examine the dynamic response properties of the so-named exceptional strong ground motions having high peak ground accelerations(PGAs), using a set of recorded motions, the PGAs of which fall in the range greater than or equal to 0. 5 in G. Secondly we evaluate response losses of a building structural system when the time differences of input excitation are included among the multi-supporting foundations of the system. We have reached the conclusive remarks that the so-named exceptional strong ground motions with high PGAs will generally have dominant periods of motion in short period ranges, and that the greater the time differences of input excitation for the system are taken, the lesser the responses of structural system are yielded when compared to those with uniform input excitation.
