Description of the NDE1.0 flat file

Over the last two decades, seismic ground motion prediction has been significantly improved thanks to the development of shared, open, worldwide databases (waveform and parametric values). Unlike seismic ground motion, earthquake data recorded in buildings are rarely shared. However, their contribution could be essential for evaluating the performance of structures. Increasing interest in deploying instrumentation in buildings gives hope for new observations, leading to better understanding of behavior.

This flat-file provides information on earthquake responses of instrumented buildings. The structure of the NDE1.0 flat-file contains structural response parameters (i.e. drift ratio, peak top values of acceleration, velocity and displacement, pre- and co-seismic fundamental frequencies) computed for several intensity measures characterizing ground motion (i.e. peak ground values of acceleration, velocity and displacement, spectral values, Arias intensity, strong motion duration, cumulative absolute velocity, destructive potential). The data are from real earthquake recordings collected in buildings over the years. Some building, site and earthquake characteristics are also included (i.e. structural design, shear wave velocity, magnitude, epicentral distance, etc.). This 1.0 version contains 8520 strong motion recordings that correspond to 118 buildings and 2737 events, providing useful information for analyses related to seismic hazard, variability of building responses, structural health monitoring, nonlinear studies, damage prediction, etc.

This work is part of the URBASIS program led by Philippe Guéguen at ISTerre/Université de Grenoble Alpes. The strong motion data were obtained from the BRI Strong Motion Observation (http:// smo.kenken.go.jp/). Part of this work was supported by the Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe (SERA), a project funded by the EU Horizon 2020 program under Grant Agreement Number 730900.
