In order to make sure the structures have well seismic performance, the designer adopt dynamic time-history analysis method.But there is a problem to calculate the dynamic response of the structures which is how to find a scientific and reasonable criterion to select seismic wave records. In order to solve this problem and find a scientific and proper criterion to select seismic wave records, this paper referred to the standards ruled by the new Chinese Seismic Design Code for hydraulic structures and used the numerical analysis and scientific computation, conducted a well meticulous analysis, then put forward one way to select seismic records for time-history analysis method of hydro-structure. Except for taking the site condition, the fortified intensity, the duration into consideration, the author also give more emphasis on the fitting degree between the response spectra of seismic records with the new code to provide better fitting degree.
