| 摘 要： | 文中以某一实际工程为例,讨论工程场地地震安全性评价中加速度反应谱规准化对工程场地地震位移时程所带来的影响。数值结果表明,根据规准化加速度反应谱得出的位移时程存在很大的误差。建议在工程场地地震安全性评价工作中,不宜进行加速度反应谱的标定工作。

| Abstract: | Taking an engineering project as an example, we discussed the effect of normalizing the acceleration response spectrum in the proceeding of engineering site seismic safety evaluation on the displacement time history of the site is in this paper. Our results show that the displacement time history obtained from the normalized acceleration response spectrum is of great errors. Therefore, we suggested that the normalizing proceed for acceleration response spectra in the proceeding of engineering site seismic safety evaluation is not suitable. |
