摘要：
Here, a total of 7 778 horizontal acceleration records from 156 earthquakes were collected. Based on the energy distribution and magnitude-distance cluster analysis method, 7 778 horizontal acceleration records were divided into 12 groups taken as the basic data of a ground motion record database. Based on the physical model of engineering random ground motion, 24 groups of simulated ground motions with 12 small sample groups of 100 samples each group and 12 large sample groups of 300 samples each group, under different site types, magnitudes and propagation distances, were synthesized by using the narrow band wave groups superposition method. A total of 4 800 simulated ground motion time histories were taken as the basic data of a simulated ground motion database. The database system of engineering random ground motion based on Windows system was developed by using the ground motion records after clustering and various groups of simulated ground motions to realize retrieval of ground motions, visualization of time histories, response spectra and related seismic information and data download. © 2021, Editorial Office of Journal of Vibration and Shock.
