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.
