Study on Mathematical Processing of Auto-Regressive Model (ARM) in Power Spectral Analysis of Ground Motion by Earthguake
Qihong Zhu · Journal of Shenyang Institute of Aeronautcal Engineering · 2001
This paper briefly introduces the mathematical processing of ARM used in power spectral analysis of discrete time-histories data and confirms the usalitity of ARM in earthquake engineering. This method can obtain the stable and smooth power spectral density function from a few random data and can be used for studying the non-stationary spectral characteristics of ground motion by earthguake. The achievements of the study has a certain reference value for anti-seismic design of high-rise buidings.
