The unseating prevention systems are installed in prep aration for the unexpectedly large seismic force or displacement due to larger intensity of ground motion, failure of the surrounding ground, etc. It is necessary to develop more reasonable design criteria and reliable procedures of unseating prevention system based on possible unseating scenario s. Based on observations of actua l damage from past extreme earth-quakes and analytical investigations, the required functions of unseating prevention devices and the effects of the structural propertie s of the devices are determined.
