Abstract :
A study of random motion effects reveals that broadband seismic disturbances become filtered by mechanical soil-structure systems to produce narrow-band floor response motion under the equipment. The latter corresponds to quasi-resonance vibration buildup at one or more natural frequencies of the building.
