An electric shake table system for disaster and emergency preparedness training

Abstract

This study presents the design and development of an electric shake table system. The system was used to train civilians and professional responders for disaster preparedness and emergency training. The developed system can simulate actual ground shaking by combining both horizontal and vertical shaking motions produced by the two induction motors. Moreover, the table simulation can produce intensity ranging from III to VIII in accordance to the Philippine Volcanology and Seismology (PHIVOLCS) Earthquake Intensity Scale (PEIS). The table’s motion was tested using a wireless digital seismograph to measure its effectiveness in tracking different earthquake intensities.
