Seismic Performance Evaluation of Lead High‐Damping Rubber Bearings Tested by Real‐Time Hybrid Simulations at Low Temperatures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Lead high‐damping rubber (LHDR) bearings, composed of high‐damping rubber and lead core, are effective isolation devices that address increased seismic demands. The temperature effect on the behavior of LHDR bearings is significant, leading to increased initial stiffness at low temperatures.
