“…The reinforcing plates as well as the leadbronze friction plates are bonded to various layers of elastomeric by vulcanization. The sliding elastomeric bearing pads act as a filter between the structure proper and the ground, the forces transmitted to the structure being dependent on the characteristics of the filter itself (Guiraud et al 1985). During low intensity earthquakes, the structure vibrates elastically on the elastomeric blocks and returns to its original position after the earthquake.…”

SUMMARYThe stationary response of base-isolated buildings subjected to earthquake excitation is studied. The frequency content of earthquake input is described by the Clough-Penzien spectral model. The response parameters of interest are (1) the rootmean-square (RMS) displacement (T, of the basement relative to the foundation (i.e. shear deformation of the isolation system) and (2) the ratio (ga/oaO) of the RMS value ofthe absolute acceleration at the roofofthe isolated structure over the corresponding value when the isolation system is locked. The variation of these response parameters with the effective frequencyf, of the base-isolated structure is investigated. As input, earthquakes with moment magnitudes M = 7.3 and M = 6.0 are considered. The acceleration spectra corresponding to these two earthquake sizes have pronouncedly different frequency content over the frequency range 0.1-1.0 Hz which is of primary importance for base-isolated structures. An important conclusion that comes from these analyses is that confidence in the effectiveness of a base-isolated system should be based primarily on its capacity to absorb/dissipate energy and less on its influence in shifting the fundamental period of the structure out of the range of dominant earthquake energy.
