1. Introduction. Servohydraulic shaking tables are used to simulate earthquake-induced ground motion for the seismic testing of large structures. Such testing is a vital part of the development of earthquake resilient buildings and infrastructure (e.g. bridges and dams), and thus plays a part in safeguarding many thousands of lives.
