【摘要】 采用完全非平稳人造地震动技术,就是在传统的考虑幅值非平稳特性拟合目标反应谱的基础上,根据不同的场地条件和地震环境,引入实际强震或地震记录提取的非平稳的相位来共同拟合目标反应谱.本项研究技术将20多年来通用人造地震动的技术进行了实用性改进,建立了人造地震动与强震、测震记录的应有联系,使天然地震记录数据的推广应用有了更多的渠道和技术保证,可以直接应用于防震减灾工程实际.更多还原

【Abstract】 A technique to generate totally non-stationary ground motion spectrum is on the base of traditional technic which only take consideration of non-stationary amplitude to fit target response spectrum.By this new method,the non-stationary phase is introduced from actual seismic or strong motion records according to the site and seismic condition to fit target response spectrum.The technique used for over 20 years in ground motion generation is improved actually by this new technique and the relationship among artificial earthquake,actual strong seismic and seismic record is also set up.This can be applied directly in earthquake protection and mitigation and makes the seismic record more widely usage.更多还原
