Division of Earthquake Disasters, DPRI


Theoretical and experimental studies are conducted with the aim of mitigating earthquake induced disasters. This division consists of researchers in geophysics, civil engineering, and architectural engineering who cooperatively investigate broad research areas from strong motion generation to life-threatening earthquake disasters. Comprehensive research on earthquake disaster mitigation is also conducted with members in the Division of Earthquake Hazards and related fields.

Strong Motion Seismology The research is focused on earthquake sources, seismic wave propagation, and site effects to study ground motion characteristics and to develop advanced methodologies of strong motion prediction for evaluating the seismic hazard from destructive earthquakes.

Dynamics of Foundation Structures Research in this section aims to 1) Integrate theories and methodologies related to the earthquake disaster mechanisms: seismic source characteristics, nonlinear soil structure response, nonlinear dynamic response of structure systems, subsurface structures, and other civil engineering structures, and 2) Develop rational seismic design methods for those structures. Major research topics are Engineering Seismology, Seismic Behavior of Structure Systems, and Development of Innovative Structures.

Structural Dynamics The main theme of this laboratory is the improvement of seismic designs of buildings, including foundations. Fundamental studies have been carried out to elucidate the dynamic characteristics of building structures with various types of foundations.
