Activity

Best base isolator

In this activity, students use a physical model to investigate the effectiveness of different properties for base isolators.

How base isolation originated

Dr Bill Robinson of Robinson Seismic, the inventor of the lead rubber bearing , talks about how he developed the bearing while he was working with Ivan Skinner at the Department of Scientific and Industrial Research in the early 1970s.
