【摘要】 针对工程抗震分析中所必需的加速度数据及我国实测地震记录的缺乏,介绍了一种合成具有较高收敛精度的人工地震动的简易方法——时域法。结合工程实例,用时域法生成了与《水工建筑物抗震设计规范》规定的设计反应谱相拟合的人工地震动时程,实现了地震动的人工合成。更多还原

【Abstract】 Time domain method,as a simple method of high precision is presented,which is used to generate artificial earthquake wave,aimed at the data of acceleration and seismic records are lack in engineering earthquake-proof.In connection with an engineering practice,artificial earthquake has been generated from the time-domain method,which fitted with the response spectrum decided by 《The Seismic Design Code of Hydraulic Structure》,realized artificial synthesis of the earthquake.The results of which have been used in the seismic analysis of practical engineering.更多还原
