Experimental Study of Seismic Isolation Systems with Emphasis on Secondary System Response and Verification of Accuracy of Dynamic Response History Analysis Methods

by  Eric D. Wolff and Michael C. Constantinou

This report provides an assessment of the validity and accuracy of analysis methods commonly used for seismically isolated structures, emphasizing secondary system response, contemporary seismic isolation systems, and strong and/or near fault seismic excitation. Eight isolation systems were studied: low damping elastomeric bearings with and without linear and nonlinear viscous dampers, Friction Pendulum bearings with and without linear and nonlinear viscous dampers, low damping elastomeric bearings with lead cores and low damping elastomeric bearings in conjunction with flat sliding bearings. A large body of additional information, which is not included in the printed report, is available from this site. The appendices are provided below  in PDF format.
