Urgency of the study of long-period ground motion;
长周期地震动衰减关系研究的迫切性
2.
This paper investigates long-period ground motion characteristics of the 1999 Jiji(Chi-Chi), Taiwan, mainshock and aftershocks on the basis of a lot of the high quality digital strong motion records.
用丰富的高质量数字强震记录对台湾集集大地震及余震的长周期地震动特性进行了研究。
3.
At present,the research on the attenuation relationship of long-period ground motion and the long-period response spectrum is not well developed and there are not many research projects about long-period seismic response for high-rise structures subjected to long-period ground motion.
目前,对长周期地震动衰减关系和长周期反应谱的研究尚不成熟,对长周期地震动作用下高层建筑结构的地震响应研究还比较少。
