China Earthquake Administration performed mobile observation of strong ground motion induced by the aftershocks.

The design and implementation of the system of Tianjin digital strong motion metwork

Both the observation of strong motion of bridges and the vibration monitoring of bridge structures help to reach the final goal of reducing the earthquake disaster.

Analysis of blasting vibration intensity based on finite element numerical calculation;

Physical simulation study on dynamic failures of layerad rock masses under strong ground motion;

To study the characteristics of inelastic response spectra,an attenuation relationship is established for inelastic response spectra involving earthquake magnitude,source-to-site distance,and site class based on 266 strong ground motion records which collected from 15 strong earthquakes in California of America.

Based on 266 strong ground motion records from 15 significant earthquakes in California of America, an attenuation relationship was developed for ground motion hysteretic spectra with earthquake magnitude, source-to-site distance, and site class.

This paper introduces the principle and specification of model GDQJ-1 A strong motion data collection system.
