摘要:
标准地震动记录集只考虑设定地震信息而与结构自振周期无关,具有普遍的适用性。但是目前的设定地震信息主要是确定性设定地震,并且没有经过目标谱匹配,因此采用标准地震动记录集的结构地震反应离散性较大。文中采用最新的适用于我国强震区的地震动预测方程,构建我国4类地震区的设定谱,通过同时匹配设定谱的平均值和标准差,给出适用于我国4类地震区的标准地震动记录集,可为工程结构抗震设计提供可行的地震动记录选用建议和调幅系数推荐值。
Abstract:
The standardized ground motion record sets have wide applicability due to the properties that they only consider the scenario earthquake information and have no relevance with structural vibration periods. However, the scenario earthquake information is only from deterministic scenario earthquakes, and the standardized ground motion record sets have not been matched by the target spectra, therefore, there will be large variabilities in seismic responses of structures under the standardized ground motions. In this paper, the newest ground motion prediction equation(GMPE), which is suitable to the seismic areas in China, is adopted to construct the scenario spectra for the four seismic areas in China. Then, by the selection and scaling algorithm through matching both the mean and standard deviation values of scenario spectra, the standardized ground motion record sets are given for the four seismic areas in China. The results can provide the recommendations for ground motion selection and scaling factor values.
