Title

Modeling of seismic ground motions and random vibration analysis of some structures excited by the ground motions

English Abstract

Modeling of Seismic Ground Motions and Random Vibration Analysis of Some Structures Excited by the Ground Motions By Mr. Zhe Tang Thesis Supervisor: Prof. Guo-Kang Er Department of Civil and Environmental Engineering In this thesis, the power spectral density functions of the real ground acceleration caused by earthquake are modeled with the moving average method and digital filter. Several models for the regression of the power spectrum function are tested and analyzed and then the improved Kanai-Tajimi model is proposed and used for modeling power spectrums of the ground acceleration records. To testify the feasibility and effectiveness of the improved Kanai-Tajimi model, some numerical spectrum analyses on several real data records of the ground acceleration in different areas are carried out, followed by some numerical structural analysis excited by a real earthquake to show the different effects of the improved Kanai-Tajimi model in system responses.
