Dr. Ryuta Enokida – Abstract

Dr. Ryuta Enokida – E-Defense, Japan

Dr. Ryuta Enokida is a Research Fellow at E-Defense of National Research Institute of Earth Sciences and Disaster Resilience (NIED) that has a shaking table of dimensions 20 m × 15 m with the maximum loading capacity of 1200 tonne. Dr. Enokida received his Ph.D. in 2012 from the Department of Architecture and Architectural Engineering, Kyoto University (this is tantamount to the Department of Civil Engineering in the European university systems). He was awarded postdoctoral research fellowships for a four-year international research by the Japan Society for the Promotion of Science (JSPS) and engaged in control of nonlinear systems and dynamical substructuring experiments at the Department of Mechanical Engineering, University of Bristol in the UK. He has expertise in the control of actuation systems (shaking table tests and servo hydraulic actuators), automatic control theory, signal processing, system identification, health monitoring and structural dynamics. After he joined E-Defense in 2016, he mainly works on: 1) new experimental methodologies for actuation systems; 2) system identification of parametric changes of structural systems; and 3) control of highly nonlinear structural systems.


ABSTRACT - E-Defense, Japan

National Research Institute for Earth Science and Disaster Resilience (NIED) has a prestigious earthquake testing facility, commonly known as E-Defense that has the world largest three-dimensional shaking table with the size of 20 m × 15 m and the maximum loading capacity of 1200 tonne. This facility has contributed to national and international earthquake engineering communities via execution of near a hundred experiments for various types of structures. We briefly introduce a historical note of achieved experiments at E-Defense since its commencement in 2005.
