摘　　要：利用福建数字强震动台网历年各类典型加速度记录的相位谱拟合所在场地设计反应谱,获得具有本地区不同场地、不同分向天然地震记录的非平稳性特征又满足抗震设防要求的场地设计地震波,同时提供了具体的应用算例及可供福建地区建筑结构时程分析时选用的输入地震波。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.
