Synthesize Site Design Earthquake Waves Using Acceleration Records of Province-Level Digital Strong Motion Network

In this paper, a method of using different types of acceleration records from Fujian digital strong motion network during past years is studied. Through extracting phase spectra and generating site design response spectra, site design earthquakes with non-stationary property of natural earthquake records of horizontal and vertical components for different types of sites in the area and also satisfying seismic fortification criteria are obtained. Applicable examples and selected site design earthquakes for time history analysis of building structures in Fujian area are also provided. The result provides a practical and valuable application in earthquake engineering.
