EXPERIMENTAL STUDY OF THE DYNAMIC BEHAVIOUR OF HIGH DAMPING RUBBER BEARING ISOLATOR

摘要：

High-damping rubber bearing isolator (HDR) has become as an effective device to enhance the seismic resistance for ridge, the lead rubber isolators (LRB) as well. However, the dynamic characteristics of the HDR isolators have not always been clarified so far because of their scatter nature of mechanical properties and the lack of reliable test data. In this study, new type of HDR isolator is tested dynamically under different conditions. Using the test results, the relationships between the equivalent stiffness, damping ratio and number of cycles as well as the magnitude of shear strain were examined.
