Abstract
High damping rubber bearings contain quite complex hysteretic behaviours, which cannot be represented accurately by a simple model. For seismic response analyses of structures supported and isolated by high damping rubber bearings, an accurate model is necessary to characterise the hysteretic laws correctly. Hysteretic performance tests were carried out and some hysteretic laws found from the test results include: the hysteretic loop of high damping rubber bearings is symmetrical in the positive and negative directions and a hysteretic envelope loop is found; for different hysteretic loops starting at the same loading location, the increasing tendency of the shear force is similar in the beginning while a certain difference is found at the end; hysteretic curves between two existing ones could be calculated by the linear interpolation method. These laws would be conducive to a more accurate hysteretic model to analyse the dynamic response of high damping rubber bearings.
