| Abstract: | In this paper, with the method of extracting non-stationary phase data from natural seismic record, the feasibility and rationality for artificial ground motion record method are demonstrated. As an example, the new method is applied for generating the non-stationary artificial ground shocking at the rock site of Huhhot city area which to pick up the non-stationary phase of natural seismic record from the feel earthquake for the response spectrum compatible. The method makes more strong relationship between the digital record of seismic observation and the ground strong motion evaluation of structure. And this evaluation has been a qualitative leap. |
| Keywords: | seismic record phase non-stationary artificial ground motion response spectrum |
