Two New Types of Seismic-Isolation Device

According to conventional earthquake resistance strategy, most structures are considered fixed to the ground at their footings. Therefore, when an earthquake occurs, its seismic waves can transmit in an unimpeded manner throughout the structure, causing forced vibrations in the superstructure. Under these circumstances the dynamic behaviour of the structure can magnify the response to ground movements caused by the quake. Professor T.-Q. Song and Professor W.-J. Wang
