Modeling and generation of seismic ground motion for active control in civil engineering

摘要

The Artificial Accelerograms have been developed for assessing the dynamic response of structures. Considering seismological properties of the site are necessary for the best simulation of accelerograms. In a simplified seismic analysis, we model only the strong phase of the seismic signal. The latter is then assumed to be stationary during this period. In this study have used models Kanai-Tajimi and Clough-Penzien to generate the seismic signals and see their effect on the structure. We presents a general procedure for the modelisation and generation of earthquake ground motions based on parametric ARMA model with introducing soil-structure interaction (SSI).
