【摘要】 本文介绍了1990年2月10日苏南地震时上海吴泾观测台站得到的自由场记录以及数字强震记录数据处理的方法。并且给出了已校正后的吴泾自由场的加速度、速度、位移地震记录曲线,以及它们的反应谱和富里叶幅值谱的结果。过去在上海没有自己的地震记录,结构抗震分析往往要借用于国外的或外地的地震记录,由于场地土的影响不同,这就给计算分析带来了很大的近似性。这次地震记录的取得为上海的地面运动以及地震工程研究积累了有益的资料。更多还原

【Abstract】 In this paper the earthquake records obtained at free field from WUJING strong motion observation station in Shanghai of SUNAN earthquake on Feb. 10,1990 and the process method of digital strong motion data are introduced. The corrected earthquake records of acceleration, velocity, displacement at WUJING free field and their response spectrum as well as Fourier spectrum are given. In the past there was not any earthquake record in Shanghai, therefore all earthquake resistance analyses of structures need to employ some records from abroad or from other provinces in China. Large approximation is introduced in the calculation and analysis due to the effects of the different field soils. These earthquake records are added to the valuable data for the researches of strong ground motion and earthquake engineering in Shanghai.更多还原
